Have you tried simply &#39;reboot&#39; with adb?

      adb reboot

Also you can run complete shell scripts (e.g. to reboot your emulator) via adb:

     adb shell &lt;command&gt;

The official docs can be found [here][1].


  [1]: https://developer.android.com/studio/command-line/adb

You can reboot the device by sending the following broadcast:

```$ adb shell am broadcast -a android.intent.action.BOOT_COMPLETED```

`adb reboot` should not reboot your linux box.

But in any case, you can redirect the command to a specific adb device using `adb -s &lt;device_id&gt; command` , where  

Device ID can be obtained from the command `adb devices`  
command in this case is `reboot`

I think the only way to do this is to run another machine in parallel and use that machine to issue commands to your android box similar to how you would with a phone. If you have issues with the IP changing you can reserve an ip on your router and have the machine grab that one instead of asking the routers DHCP for one. This way you can ping the machine and figure out if it&#39;s done rebooting to continue the script.

I am looking at the Hibernate `hbm2ddl.auto` configuration property and its possible values:

- `validate`
- `update`
- `create`
- `create-drop`

What do all these values do?

The [Hibernate Reference Documentation][1] only talks briefly about `create-drop`, but doesn&#39;t say anything about the other values:

&gt; `hibernate.hbm2ddl.auto`
&gt;
&gt; Automatically validates or exports schema DDL to the database when the `SessionFactory` is created. With `create-drop`, the database schema will be dropped when the `SessionFactory` is closed explicitly.
&gt;
&gt; __e.g.__ `validate` | `update` | `create` | `create-drop`

I found _very_ useful explanations in these Stack Overflow questions:

- [Hibernate hbm2ddl.auto possible values and what they do?][2]
- [Schema is not dropped on hbmddl.auto = create.drop][3]

But still nothing in the official documentation.

we have android + linux m/c, we log in into linux shell and boot the machine in android GUI.
now we have the some script that is running on the same machine through linux shell. In that case when the script hangs we need to restart android machine. but it result into restarting the linux machine too. as they are on same machine. so i need the way to restart the android so it comes out of hang state and control remains on the script that is running through the linux shell.

so is there any adb or linux command that work for me?

I have a `GridView`. The data of `GridView` is request from a server.

Here is the item layout in `GridView`:

I request data from server, get image url and load image to `Bitmap`

    public static Bitmap loadBitmapFromInputStream(InputStream is) {
        return BitmapFactory.decodeStream(is);
    }

    public static Bitmap loadBitmapFromHttpUrl(String url) {
        try {
            return loadBitmapFromInputStream((InputStream) (new URL(url).getContent()));
        } catch (Exception e) {
            Log.e(TAG, e.getMessage());
            return null;
        }
    }

and there is the code of `getView(int position, View convertView, ViewGroup parent)` method in adapter

    Bitmap bitmap = BitmapUtil.loadBitmapFromHttpUrl(product.getHttpUrl());
    prodImg.setImageBitmap(bitmap);

The image size is `210*210`. I run my application on my Nexus 4. The image does fill `ImageView` width, but the `ImageView` height does not scale. `ImageView` does not show the whole image.

How do I solve this problem?

Using SimpleXML with Android and Gradle

I have an `Activity` with a `ViewPager`. I also have a `Dialog` that will retrieve a list with some items that the user will choose. Now, how can I update the `Fragment` where the Items are supposed to display as new views attached to this Fragment? 

Here is my `ViewPager`&#39;s adapter:

    public static class MyAdapter extends FragmentPagerAdapter {
        public MyAdapter(FragmentManager fm) {
            super(fm);
        }
 
        @Override
        public int getCount() {
            return 1;
        }
 
        @Override
        public android.support.v4.app.Fragment getItem(int position) {
            switch (position) {
            case 0:
                return new Fragment1();
             
            default:
                return null;
            }
        }
    }

Now, here is the `Fragment`:

    public class Fragment1 extends Fragment{
    
	@Override
	public void onActivityCreated(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onActivityCreated(savedInstanceState);
	}

	@Override
	public void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
	}

	@Override
	public ViewGroup onCreateView(LayoutInflater inflater, ViewGroup container,
			Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		ViewGroup view = (ViewGroup)inflater.inflate(R.layout.screen1, container, false);
		}
		return view;
	}

    }

This is the method that I want to use to add Items to my `Fragment`

    private void addItem() {
    	
        // Instantiate a new &quot;row&quot; view.
    
    	final ViewGroup[] newViews = new ViewGroup[selectedItems.length];
    	
    	    	
    	for(int i = 0; i &lt; selectedItems.length; i++){
    		newViews[i] = (ViewGroup) LayoutInflater.from(this).inflate(
    	                R.layout.animated_layout_item, mContainerView, false);
    		
    		// Set the text in each new row.
    		((TextView) newViews[i].findViewById(android.R.id.text1)).setText(selectedItems[i]);
    		
    		// Because mContainerView has android:animateLayoutChanges set to true,
            // adding this view is automatically animated.
    		   		
    			mContainerView.addView(newViews[i], 0);
    			
    			
    	    // Set a click listener for the &quot;X&quot; button in the row that will remove the row.
    		OnClickListener listener = new MyAddItemListener(newViews[i], mContainerView, this);
    		newViews[i].findViewById(R.id.delete_button).setOnClickListener(listener);
    	
    	}
    	
    	
    }

I am creating task manager. I have tasklist and I want when I click on particular tasklist name if it empty then it goes on Add Task activity but if it has 2 or 3 tasks then it shows me those tasks into it in list form.

I am trying to get count in list. my database query is like:

    public Cursor getTaskCount(long tasklist_Id) {
 
		SQLiteDatabase db = this.getWritableDatabase();
		Cursor cursor= db.rawQuery(&quot;SELECT COUNT (*) FROM &quot; + TABLE_TODOTASK + &quot; WHERE &quot; + KEY_TASK_TASKLISTID + &quot;=?&quot;,
				 new String[] { String.valueOf(tasklist_Id) });
		if(cursor!=null &amp;&amp; cursor.getCount()!=0)
	          cursor.moveToNext();
		return cursor;
	}    

In My activity:

    list_tasklistname.setOnItemClickListener(new OnItemClickListener() {
		@Override
		public void onItemClick(AdapterView&lt;?&gt; arg0,
				android.view.View v, int position, long id) {
					db = new TodoTask_Database(getApplicationContext());
					Cursor c = db.getTaskCount(id);
					System.out.println(c.getCount());
					if(c.getCount()&gt;0) {	
					System.out.println(c);
					Intent taskListID = new Intent(getApplicationContext(), AddTask_List.class);
					task = adapter.getItem(position);
					int taskList_id = task.getTaskListId();
					taskListID.putExtra(&quot;TaskList_ID&quot;, taskList_id);
					startActivity(taskListID);
				}
				else {
					Intent addTask = new Intent(getApplicationContext(), Add_Task.class);
					startActivity(addTask);
				}
			}
		});
		db.close();
	}

but when I am clicking on tasklist name it is returning 1, bot number of tasks into it.

OK, logcat is showing system logs but it is not showing application log on my Huawei Ascend. If I switch to another device such as my Galaxy Nexus or Nexus 7 then for the same app (same APK even) log is displayed.

The Huawei Ascend is running Android 4.1.1, it has USB debugging switched on in developer options. This occurs for logcat run from either the command line or from IntelliJ. And I&#39;m making sure that the correct device is selected - in fact I&#39;m only plugging a single device in at a time. I&#39;ve tried restarting adb, clearing it&#39;s buffer etc

I can see that the app is starting on the Huawei, I even get system logs showing that the Activity has started. But unlike on the other devices I get no app log in the Activity#onCreate (or from anywhere else).

I need to view my SQLite db but I don&#39;t know how to do it. I&#39;ve gone to http://www.sqlite.org/download.html and downloaded the command line shell for my OS, but when I run the program and type `adb ...` I get errors.

Note: I&#39;m using Android Studio so I&#39;m assuming I don&#39;t need to install anything extra because I recall Android Studio said it had all the SDK tools needed.

How to use ADB in Android Studio to view an SQLite DB

On a non-rooted android device, I can navigate to the data folder containing the database using the `run-as` command with my package name. Most files types I am content with just viewing, but with the database I would like to pull if from the android device.

Is there a `download` `copy` or `move` command from this part of adb shell? I would like to download the database file and view its content using a database browser.

One answer here involves turning entire application package into a compressed archive, but there is no further answer on how to extract that archive once this is done and moved to the machine, leaving me very sidetracked when there might be a more direct solution to begin with

Retrieve database or any other file from the Internal Storage using run-as


I was trying to use adb over TCP/IP. I have followed these steps

    adb tcpip 5555

I have used my device for 2 days and now I am unable to connect to my IP address like when I do

    adb tcpip 5555

it doesn&#39;t respond anything. Anyone knows what could be the scenario.

I have a set of data in an SQLite database. I need to view the database on a device. How do I do that?

I have checked in ddms mode. The data in file explorer is empty.


How do I view the SQLite database on an Android device?

So in 4.3 there was a concept of System applications. APKs that were placed in `/system/app` were given system privileges. As of 4.4, there is a new concept of &quot;privileged app&quot;. Privileged apps are stored in `/system/priv-app` directory and seem to be treated differently. If you look in the AOSP Source code, under `PackageManagerService`, you will see new methods such as

    static boolean locationIsPrivileged(File path) {
        try {
            final String privilegedAppDir = new File(Environment.getRootDirectory(), &quot;priv-app&quot;)
                    .getCanonicalPath();
            return path.getCanonicalPath().startsWith(privilegedAppDir);
        } catch (IOException e) {
            Slog.e(TAG, &quot;Unable to access code path &quot; + path);
        }
        return false;
    }


So here is an example of a situation where these differ. 

    public final void addActivity(PackageParser.Activity a, String type) {
    ...
    if (!systemApp &amp;&amp; intent.getPriority() &gt; 0 &amp;&amp; &quot;activity&quot;.equals(type)) {
                    intent.setPriority(0);
                    Log.w(TAG, &quot;Package &quot; + a.info.applicationInfo.packageName + &quot; has activity &quot;
                            + a.className + &quot; with priority &gt; 0, forcing to 0&quot;);
                }
    ...

This affects the priority of any activities that are not defined as system applications. This seems to imply you can not add an activity to the package manager whose priority is higher than 0, unless you are a system app. This does **not** preclude privileged apps as far as I can tell (there is a lot of logic here, I may be wrong.). 

My question is what exactly does this imply? If my app is privileged, but not system, what difference will that make? In `PackageManagerService` you can find various things that differ between system and privileged apps, they are not exactly the same. There should be some kind of ideology behind privileged apps, otherwise they would have just said:

    if locationIsPrivileged: app.flags |= FLAG_SYSTEM

and been done with it. This is a new concept, and I think it would be important to know the difference between these kinds of apps for anyone who is doing AOSP development as of 4.4.

What is the difference between system apps and privileged apps on Android?

I would like to modify Android OS (official image from AOSP) to add preprocessing to a normal phone call playback sound.

I&#39;ve already achieved this filtering for app audio playback (by modifying *HAL* and *audioflinger*).

I&#39;m OK with targeting only a specific device (Nexus 5X). Also, I only need to filter playback - I don&#39;t care about recording (uplink).

*UPDATE #1:* 

To make it clear - I&#39;m OK with modifying Qualcomm-specific drivers, or whatever part that it is that runs on Nexus 5X and can help me modify in-call playback.


*UPDATE #2:* 

I&#39;m attempting to create a Java layer app that routes the phone playback to the music stream in real time.

I&#39;ve already succeeded in installing it as a system app, getting permissions for initializing `AudioRecord` with `AudioSource.VOICE_DOWNLINK`. However, the recording gives blank samples; it doesn&#39;t record the voice call.

This is the code inside my worker thread:

    // Start recording
    int recBufferSize = AudioRecord.getMinBufferSize(44100, AudioFormat.CHANNEL_IN_STEREO, AudioFormat.ENCODING_PCM_16BIT);
    mRecord = new AudioRecord(MediaRecorder.AudioSource.VOICE_DOWNLINK, 44100, AudioFormat.CHANNEL_IN_STEREO, AudioFormat.ENCODING_PCM_16BIT, recBufferSize);

    // Start playback
    int playBufferSize = AudioTrack.getMinBufferSize(44100, AudioFormat.CHANNEL_OUT_STEREO, AudioFormat.ENCODING_PCM_16BIT);
    mTrack = new AudioTrack(AudioManager.STREAM_MUSIC, 44100, AudioFormat.CHANNEL_OUT_STEREO, AudioFormat.ENCODING_PCM_16BIT, playBufferSize, AudioTrack.MODE_STREAM);

    mRecord.startRecording();;
    mTrack.play();

    int bufSize = 1024;
    short[] buffer = new short[bufSize];
    int res;
    while (!interrupted())
    {
        // Pull recording buffers and play back
        res = mRecord.read(buffer, 0, bufSize, AudioRecord.READ_NON_BLOCKING);
        mTrack.write(buffer, 0, res, AudioTrack.WRITE_BLOCKING);
    }

    // Stop recording
    mRecord.stop();
    mRecord.release();
    mRecord = null;

    // Stop playback
    mTrack.stop();
    mTrack.release();;
    mTrack = null;


I&#39;m running on a Nexus 5X, my own AOSP custom ROM, Android 7.1.1. I need to find the place which will allow call recording to work - probably somewhere in `hardware/qcom/audio/hal` in platform code.

Also I&#39;ve been looking at the function `voice_check_and_set_incall_rec_usecase` at `hardware/qcom/audio/hal/voice.c` However, I wasn&#39;t able to make sense of it (how to make it work the way I want it to).

*UPDATE #3:*

  I&#39;ve opened [a more-specific question](https://stackoverflow.com/questions/43818736/call-recording-make-audiosource-voice-downlink-work-on-nexus-5x-rooting-or-cu) about using `AudioSource.VOICE_DOWNLINK`, which might draw the right attention and will eventually help me solve this question&#39;s problem as well.
