The app closes due to getting permissions without any error messages

My application is closed immediately after launching due permission request without an errors. This is my code, is here something wrong? Also, I post manifest file here to let you check it. I need bluetooth permission and data access.
The probem is in this line:
ActivityCompat.requestPermissions(this, permissions, REQUEST_MICROPHONE);
If I comment this, application will not close after launching.
private static final int REQUEST_MICROPHONE = 1;
private void askPermissions(){
String[] permissions = {Manifest.permission.RECORD_AUDIO,
Manifest.permission.BLUETOOTH,
Manifest.permission.BLUETOOTH_ADMIN,
Manifest.permission.ACCESS_FINE_LOCATION,
Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.BLUETOOTH_SCAN,
Manifest.permission.BLUETOOTH_CONNECT};
if (!hasPermissions(permissions)) {
ActivityCompat.requestPermissions(this, permissions, REQUEST_MICROPHONE);
}
}
private boolean hasPermissions(String[] permissions) {
if(permissions != null){
for(String perm : permissions){
if(ContextCompat.checkSelfPermission(this, perm) != PackageManager.PERMISSION_GRANTED)
return false;
}}
return true;
}
And the Manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.myapp">
<uses-sdk android:minSdkVersion="21"

It was discrepancy between Android version and way to get permissions. Unfortunately, it was not any errors or other communications and I have to find a problem by luck.

Load WebExtensions on GeckoView

I'm working with GeckoView and met problem with installing AddOns. As suggested on Documentation, I've provided XPI compatible with Android, but nothing changes. Copying file to Assets doesn't make a change. Browser doesn't acknowledge WebExtension.
private fun setupGeckoView() {
geckoSession?.permissionDelegate = object : GeckoSession.PermissionDelegate {
override fun onContentPermissionRequest(
session: GeckoSession,
perm: GeckoSession.PermissionDelegate.ContentPermission
): GeckoResult<Int>? {
return super.onContentPermissionRequest(session, perm)
}
}
geckoView = findViewById(R.id.geckoView)
val runtime = GeckoRuntime.create(this)
runtime.settings.consoleOutputEnabled = true
runtime.webExtensionController.promptDelegate = PromptListener(runtime.webExtensionController)
runtime.webExtensionController
.install("https://addons.mozilla.org/android/downloads/file/3719055/youtube_high_definition-85.0.0-an+fx.xpi")
geckoSession.open(runtime)
geckoView.setSession(geckoSession)
geckoSession.loadUri("https://www.youtube.com")
}

I'm checking logs and the result is confusing. I've got prompt that WebExtension is installed, but when I looking at controller.list() it's empty.

You may be missing a PermissionDelegate:
geckoSession?.permissionDelegate = object : GeckoSession.PermissionDelegate {
override fun onContentPermissionRequest(
session: GeckoSession,
perm: GeckoSession.PermissionDelegate.ContentPermission
): GeckoResult<Int>? {
return super.onContentPermissionRequest(session, perm)
}
}
Permission delegate allows you to handle requests from Gecko for any permission that needs handling.

GCM unable to start service intent

starting on android P my app is not able to register for a GCM ID. My PushManager code looks like

I've found that devices running older OSs register fine. the only issue I've had with this so far is with the android P preview. Any help would be appreciated.

You are likely be using an older version of GCM.
You may upgrade to GCM 11 or higher, or even better, migrate to FCM. (GCM is now deprecated)
(The latest GCM version is 15.0.1: com.google.android.gms:play-services-gcm:15.0.1)

Closed 1 year ago.
i am developing an android app which has an flash option which is set to auto mode,but it crashes at camera.open.I have used intent to open camera
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
int result = context.checkCallingOrSelfPermission(Manifest.permission.CAMERA);
int result2 = context.checkCallingOrSelfPermission(Manifest.permission.FLASHLIGHT);
if((result==PackageManager.PERMISSION_GRANTED) && (result2==PackageManager.PERMISSION_GRANTED)) {
cam = Camera.open();
Camera.Parameters p = cam.getParameters();
p.setFlashMode(Camera.Parameters.FLASH_MODE_ON);
cam.setParameters(p);
cam.startPreview();
}
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
startActivityForResult(cameraIntent,CAMERA_CAPTURE_IMAGE_REQUEST_CODE);
}});

I may be wrong(because I don't see your Manifest.xml file) but there are two solutions I can see
1) The camera cannot be connected to because it is already being used by a different application
You cannot fix that. If the camera is occupied, you can't open it.
2) You haven't requested the Camera-permission.
This can be solved. In your manifest:
<uses-permission android:name="android.permission.CAMERA"/>
And if you are targeting android 6 you have to request the permission at runtime. For that, see this link.
EDIT:
Make sure you add all of these. This will give your app access to the camera and flashlight in software and hardware.
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.FLASHLIGHT" />
<uses-feature android:name="android.hardware.camera"/>
<uses-feature android:name="android.hardware.camera.flash"/>
Using these without requiring them makes the app not work if the device (against all odds) doesn't have a camera

you should use all these permissions
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.FLASHLIGHT" />
<uses-feature android:name="android.hardware.camera" android:required="false" />
<uses-feature android:name="android.hardware.camera.flash"
android:required="false" />
Maybe this can help but i am not sure
<permission android:name="android.permission.FLASHLIGHT"
android:permissionGroup="android.permission-
group.HARDWARE_CONTROLS"
android:protectionLevel="normal"/>

Android permission dialog not displaying

I have found a few other questions about this issue but none of the answers have solved it for me. I'm trying to request the fine location permission, but there is no dialog shown. Here's what I'm doing:
int permissionCheck = ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION);
if(permissionCheck == PackageManager.PERMISSION_GRANTED) {
Log.d("Location","Location permission already granted"); // Not logged
// Do other stuff
}
else {
Log.d("Location", "Requesting location permission"); // This is logged
ActivityCompat.requestPermissions(this,
new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION}, REQUEST_CODE_ENABLE_LOCATION);
}
No dialog appears, and onRequestPermissionsResult is not called.
This is the manifest:

Here are some tidbits from the gradle file:
compileSdkVersion 23
buildToolsVersion '21.1.2'
defaultConfig {
minSdkVersion 12
targetSdkVersion 23
}
This is in a FragmentActivity, don't know if that matters. I have uninstalled the app and run it so there should be no permissions already accepted. This is on a Nexus 7 running 6.0.

Why not try this library: https://github.com/tajchert/Nammu. It worked for me.
Nammu.askForPermission(activity, String[] permissions, new PermissionCallback() {
#Override
public void permissionGranted() {}
#Override
public void permissionRefused() {}
});
EDIT
I created a library that encapsulates the whole thing and makes it much more easier. It also shows a customisable explanation dialog before the actual request.
Use this library: https://github.com/ayz4sci/permissionHelper
Usage:
To perform an action that requires Android permission, call permissionHelper.verifyPermission. It accepts the following parameters:
String [] - description of each permission required, this will be displayed to the user in the explanation dialog.
String [] - an array of Manifest permissions
PermissionCallback - you put the actions you want to perform when permission is granted or rejected.
See example below:
permissionHelper.verifyPermission(
new String[]{"dial this number", "take picture"},
new String[]{Manifest.permission.CALL_PHONE, Manifest.permission.CAMERA},
new PermissionCallback() {
#Override
public void permissionGranted() {
//action to perform when permission granteed
}
#Override
public void permissionRefused() {
//action to perform when permission refused
}
}
);
