ActivityCompat.requestPermissions not showing dialog box

if (ContextCompat.checkSelfPermission(RegisterActivity.this,      Manifest.permission.READ_PHONE_STATE) == PackageManager.PERMISSION_DENIED){
            ActivityCompat.requestPermissions(this,
                    new String[]{Manifest.permission.READ_PHONE_STATE}, REQUEST_READ_PHONE_STATE_PERMISSION);

i'm trying to use this function on nexus 5 api 23 and its just not showing me the dialog box like its supposed to do, it's just not doing anything. what could cause the problem? (this code is in the java activity) i tried changing my minimum api to 23 and use the requestPermissions() without the ActivityCompat but still not working.

apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "23.0.2"

defaultConfig {
    applicationId "com.example.idanayzen.photomap"
    minSdkVersion 23
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'

compile 'com.google.android.gms:play-services:8.4.0'
compile 'com.android.support:design:23.1.1'
}

and the Manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.idanayzen.photomap">

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

    android:theme="@style/AppTheme">


    <meta-data

        android:label="@string/title_activity_maps" />
    <activity android:name=".RegisterActivity">

            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".WrongPhoneNum"></activity>
</application>

</manifest>

Here's an example of using requestPermissions():

First, define the permission (as you did in your post) in the manifest, otherwise, your request will automatically be denied:

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

Next, define a value to handle the permission callback, in onRequestPermissionsResult():

private final int REQUEST_PERMISSION_PHONE_STATE=1;

Here's the code to call requestPermissions():

private void showPhoneStatePermission() {
    int permissionCheck = ContextCompat.checkSelfPermission(
            this, Manifest.permission.READ_PHONE_STATE);
    if (permissionCheck != PackageManager.PERMISSION_GRANTED) {
        if (ActivityCompat.shouldShowRequestPermissionRationale(this,
                Manifest.permission.READ_PHONE_STATE)) {
            showExplanation("Permission Needed", "Rationale", Manifest.permission.READ_PHONE_STATE, REQUEST_PERMISSION_PHONE_STATE);
        } else {
            requestPermission(Manifest.permission.READ_PHONE_STATE, REQUEST_PERMISSION_PHONE_STATE);
        }
    } else {
        Toast.makeText(MainActivity.this, "Permission (already) Granted!", Toast.LENGTH_SHORT).show();
    }
}

First, you check if you already have permission (remember, even after being granted permission, the user can later revoke the permission in the App Settings.)

And finally, this is how you check if you received permission or not:

@Override
public void onRequestPermissionsResult(
        int requestCode,
        String permissions[],
        int[] grantResults) {
    switch (requestCode) {
        case REQUEST_PERMISSION_PHONE_STATE:
            if (grantResults.length > 0
                    && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                Toast.makeText(MainActivity.this, "Permission Granted!", Toast.LENGTH_SHORT).show();
            } else {
                Toast.makeText(MainActivity.this, "Permission Denied!", Toast.LENGTH_SHORT).show();
            }
    }
}

private void showExplanation(String title,
							 String message,
							 final String permission,
							 final int permissionRequestCode) {
	AlertDialog.Builder builder = new AlertDialog.Builder(this);
	builder.setTitle(title)
			.setMessage(message)
			.setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener() {
				public void onClick(DialogInterface dialog, int id) {
					requestPermission(permission, permissionRequestCode);
				}
			});
	builder.create().show();
}

private void requestPermission(String permissionName, int permissionRequestCode) {
	ActivityCompat.requestPermissions(this,
			new String[]{permissionName}, permissionRequestCode);
}

I had the same issue and it turned out to be due to the manifest merger tool pulling in an android:maxSdkVersion attribute from a dependency.

To view the actual permissions you're requesting in your APK you can use the aapt tool, like this:

/path/to/android-sdk/build-tools/version/aapt d permissions /path/to/your-apk.apk

in my case, it printed:

uses-permission: name='android.permission.WRITE_EXTERNAL_STORAGE' maxSdkVersion='18'

even though I hadn't specified a maxSdkVersion in my manifest. I fixed this issue by changing <uses-permission> in my manifest to:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" tools:remove="android:maxSdkVersion"/>

(where the tools namespace is http://schemas.android.com/tools)

I had a need to request permission for WRITE_EXTERNAL_STORAGE but was not getting a pop-up despite trying all of the different suggestions mentioned.

The culprit in the end was HockeyApp. It uses manifest merging to include its own permission for WRITE_EXTERNAL_STORAGE except it applies a max sdk version onto it.

The way to get around this problem is to include it in your Manifest file but with a replace against it, to override the HockeyApp's version and success!

> 4.7.2 Other dependencies requesting the external storage permission (SDK version 5.0.0 and later) To be ready for Android O, > HockeySDK-Android 5.0.0 and later limit the WRITE_EXTERNAL_STORAGE > permission with the maxSdkVersion filter. In some use cases, e.g. > where an app contains a dependency that requires this permission, > maxSdkVersion makes it impossible for those dependencies to grant or > request the permission. The solution for those cases is as follows:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" tools:node="replace"/>

https://support.hockeyapp.net/kb/client-integration-android/hockeyapp-for-android-sdk#permissions-advanced

Replace:

ActivityCompat.requestPermissions(this, new String[]{"Manifest.permission.READ_PHONE_STATE"}, 225);

with:

ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_PHONE_STATE}, 225);

The actual string for that permission is not "Manifest.permission.READ_PHONE_STATE". Use the symbol Manifest.permission.READ_PHONE_STATE.

It could be not a problem with a single line of your code.

On some devices (I don't recall if it is in stock Android) the Permission dialog includes a check box labeled "Never ask again". If you click Deny with the box checked then you won't be prompted again for that permission, it will automatically be denied to the app. To revert this, you have to go into Settings -> App -> Permissions and re--enable that perm for the app. Then turn it off to deny it again. You may have to open the app before turning it off again, not sure.

I don't know if your Nexus has it. Maybe worth a try.

I updated my target SDK version from 22 to 23 and it worked perfectly.

Here is another experience I'd like to share with you guys. The problem showed up after I implemented the following code to check for BLE access permission:

final String requiredPermission = (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q && targetSdkVersion >= Build.VERSION_CODES.Q) ?
            android.Manifest.permission.ACCESS_FINE_LOCATION :
            android.Manifest.permission.ACCESS_COARSE_LOCATION;

I meant to distinguish between FINE and COARSE location permission requests, both had been defined in the manifest. When checking for ACCESS_COARSE_LOCATION permission, the "Request permission" dialog never poped up but onRequestPermissionsResult was always called with PERMISSION_DENIED (in case permission was not enabled in app settings). So I removed the check for BUILD.SDK and checked only for ACCESS_FINE_LOCATION and voilla the missing dialog showed up.

final String requiredPermission = android.Manifest.permission.ACCESS_FINE_LOCATION;

did the trick.

The Manifest source contains:

<uses-permission android:name="android.permission.COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

but the apk contained android.permission.ACCESS_FINE_LOCATION only. Sometime during build, the COARSE_LOCATION had been removed.

I hope this might help somebody having the same issue.

No matter what you do, Check if you declare Permission you need in the Manifest file.

    <!--Declaring the required permissions-->
    <uses-permission
        android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission
        android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission
        android:name="android.permission.CAMERA" />

Then go to next steps..

For me the issue was requesting a group mistakenly instead of the actual permissions.

The above information is good, but setting targetSdkVersion to 23 (or higher) is critical for Android to interpret the <uses-permission> tag in the manifest as "I will ask in code" instead of "I demand upon installation." Lots of sources will tell you that you need the <uses-permission> tag, but no one says why and if you don't have that value set, you're going to be as confused as I was for hours on end.

This just happened to me. It turned out I was requesting ALL permissions, when I needed to filter to just DANGEROUS permissions, and it suddenly started working.

fun requestPermissions() {
    val missingDangerPermissions = PERMISSIONS
            .filter { ContextCompat.checkSelfPermission(this, it) != PackageManager.PERMISSION_GRANTED }
            .filter { this.getPackageManager().getPermissionInfo(it, PackageManager.GET_META_DATA).protectionLevel == PermissionInfo.PROTECTION_DANGEROUS } // THIS FILTER HERE!

    if (missingDangerPermissions.isNotEmpty()) {
        Log.i(TAG, "Requesting dangerous permission to $missingDangerPermissions.")
        ActivityCompat.requestPermissions(this,
                missingDangerPermissions.toTypedArray(),
                REQUEST_CODE_REQUIRED_PERMISSIONS);
        return
    } else {
        Log.i(TAG, "We had all the permissions we needed (yay!)")
    }
}

I came across this problem in Samsung S8 and N8 (havent found in any other)

so the problem is in the manifest file uses-permission

<uses-permission android:name="android.permission.CAMERA"
android:requiredFeature="true" />

For some reason, the attribute android:requiredFeature is the culprit. and I haven't found the explanation on why.

to solve simply remove it,

<uses-permission android:name="android.permission.CAMERA" />

Don't forget to write the permissions without extra spaces in the manifest. In my case i had:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE " />

But look, at the end, there's an extra space. Just write it the right way

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

And it's working now

I had this same issue.I updated to buildToolsVersion "23.0.3" It all of a sudden worked. Hope this helps anyone having this issue.

I was having the same problem, and solved it by replacing Manifest.permission.READ_PHONE_STATE with android.Manifest.permission.READ_PHONE_STATE.

For me the issue was I had an invalid request code. I choose 0xDEADBEEF as a request code and it was silently failing (maybe it's cast to something smaller than 32-bit somewhere internally?) If I choose 255 everything worked fine as NightSkyDev described above.

For me the error was in the manifest: the permission was in uppercase. Android Studio suggest me the permissions in uppercase. I don't care about that and it took me two hours to fixe this problem.

The right syntaxe for permission is
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

For me the problem was that right after making the request, my main activity launched another activity. That superseded the dialog so it was never seen.

I followed the top answer, but still didn't work. This simple issue wasted me many days. For my case, I'm trying to get access for MANAGE_EXTERNAL_STORAGE. At the end, I found for this particular permission, we can't use ActivityCompat.requestPermissions(), instead I have to use Settings.ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION. And to check if the permission is there, we also need to use a different API: Environment.isExternalStorageManager() instead of ContextCompat.checkSelfPermission(), not sure why they design in such an inconsistent way cause so much confusions.

I get my issue resolved following: https://stackoverflow.com/questions/64250814/how-to-obtain-manage-external-storage-permission

And also this is mentioned in SDK document of: manage-all-files.

TL;DR: Add the following to your Manifest file:

tools:remove="android:maxSdkVersion" />

Check this article, it fixed it for me:

https://nphau.medium.com/android-request-permissions-not-showing-a-dialog-box-b7f2067d7b09

it happen to me i was running it on API 23 and i had to use the code to request permission like this code below put it on on create method. note that MY_PERMISSIONS_REQUEST_READ_LOCATION is an integer that is equal to 1 example int MY_PERMISSIONS_REQUEST_READ_LOCATION = 1:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { requestPermissions(new String[]{ Manifest.permission.ACCESS_COARSE_LOCATION},MY_PERMISSIONS_REQUEST_READ_LOCATION); }

Maybe this solution could help anyone rather than:

ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);

use :

ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);

so we add android. to Manifest.permission.WRITE_EXTERNAL_STORAGE
