USB Permissions not received by Broadcast receiver

Good evening community, I am reaching with the hopes of being educated about the following problem.
My intention with this code is to be able to handle USB permission intents in a receiver registered in a manifest file. The receiver gets USB Attached and detached actions, but not USB permissions when the user either accepts or declines the prompt.
Here is the code for the manifest, receiver and an activity to send the permissions request to the USB manager. And Finally, my target SDK is 28.
Any help is very much appreciated. Thank you very much.
public class BroadcastReceiver extends android.content.BroadcastReceiver{
public static final String USB_DEVICE_ATTACHED = "android.hardware.usb.action.USB_DEVICE_ATTACHED";
public static final String USB_DEVICE_DETACHED = "android.hardware.usb.action.USB_DEVICE_DETACHED";
public static final String USB_PERMISSION ="com.android.example.USB_PERMISSION";
#Override
public void onReceive(Context context, Intent intent) {
Context applicationContext = context.getApplicationContext();
try{
if (intent != null) {
String action = intent.getAction();
if (!TextUtils.isEmpty(action)) {
if (action.equals(USB_DEVICE_ATTACHED) || action.equals(USB_PERMISSION)){
UsbDevice device = intent.getParcelableExtra(UsbManager.EXTRA_DEVICE);
UsbManager usbManager = (UsbManager) applicationContext.getSystemService(Context.USB_SERVICE);
if (action.equals(USB_DEVICE_ATTACHED)){
if (!usbManager.hasPermission(device)){
intent.setAction(USB_PERMISSION);
intent.putExtra(UsbManager.EXTRA_PERMISSION_GRANTED, false);
intent.setClass(applicationContext, PermissionActivity.class);
applicationContext.startActivity(intent);
Toast.makeText(applicationContext, "Device Attached.", Toast.LENGTH_LONG).show();
}
else{
Toast.makeText(applicationContext, "Permissions already assigned", Toast.LENGTH_LONG).show();
}
}
else if (action.equals(USB_PERMISSION)){
if (usbManager.hasPermission(device)){
Toast.makeText(applicationContext, "USB Permissions are granted.", Toast.LENGTH_LONG).show();
}
}
}
else if (action.equals(USB_DEVICE_DETACHED)) {
Toast.makeText(applicationContext, "Device Detached.", Toast.LENGTH_LONG).show();
}
}
}
}
catch(Exception e){
Toast.makeText(applicationContext, e.getMessage(), Toast.LENGTH_LONG).show();
}
}
}
Here is the activity:
public class PermissionActivity extends android.support.v7.app.AppCompatActivity {
public static final String USB_PERMISSION ="com.android.example.USB_PERMISSION";
#Override
protected void onStart() {
super.onStart();
}
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
Context applicationContext = this.getApplicationContext();
Intent intent = getIntent();
if (intent != null )
{
if (intent.getAction().equals(USB_PERMISSION)){
if (!intent.getBooleanExtra(UsbManager.EXTRA_PERMISSION_GRANTED, false )) {
UsbDevice device = intent.getParcelableExtra(UsbManager.EXTRA_DEVICE);
if (device != null) {
UsbManager mUsbManager = (UsbManager) getSystemService(Context.USB_SERVICE);
PendingIntent mPermissionIntent = PendingIntent.getBroadcast(applicationContext, 0, new Intent(USB_PERMISSION), 0);
mUsbManager.requestPermission(device, mPermissionIntent);
Toast.makeText(applicationContext, "Requesting Permission", Toast.LENGTH_LONG).show();
}
}
}
}
finish();
}
#Override
protected void onResume() {
super.onResume();
}
}
And finally, the manifest file.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.user.usbtest">
<uses-feature android:name="android.hardware.usb.host"/>

android:theme="#style/AppTheme">
<activity

android:label="#string/app_name">
<intent-filter>

android:taskAffinity="com.example.taskAffinityUsbEventReceiver"
android:theme="#style/Theme.AppCompat.Translucent">
<intent-filter>
<action android:name="com.android.example.USB_PERMISSION"/>
</intent-filter>
</activity>
<receiver android:name=".BroadcastReceiver"
android:exported="true">
<intent-filter>
<action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED"/>
<action android:name="android.hardware.usb.action.USB_DEVICE_DETACHED"/>
<action android:name="com.android.example.USB_PERMISSION"/>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
</application>
</manifest>

I found the problem. Since Android 8.0, there are more restrictions with manifest-declared
broadcast receivers and the type of actions that can be received. The USB Permissions action is not part of the limited list of actions that can be received. Here are some links regarding this issue.

PayPal Future Payment Activity authorisation null

I am using the PayPal mobile SDK (Android) because I need access to the REST API, and I am using the Sandbox. Immediate payments work fine, but I can't get an authorization code for future payments. I have checked the developer portal and future payments are enabled, although I think this is the default for the Sandbox anyway. I am using Xamarin android (c#):

if (resultCode == Result.Ok)
{
Object auth = data.GetParcelableExtra(PayPalFuturePaymentActivity.ExtraResultAuthorization);
if (auth != null) //**THIS IS ALWAYS NULL**//

}
}
}
Complete.TrySetResult(resultCode.ToString());
Context context = MainActivity.Instance;
var intent = new Intent(context, typeof(PayPalService));
context.StopService(intent);
}
}
}
I can't go any further (i.e. server side coding) without an authorization code. The problem is the 'auth' object is always null, and I can't see anything wrong with the code as it it basically the sample code. What am I missing? Or does this only work in the live environment?
Thanks.

Made a simple error, the activity needs to be a PayPalFuturePaymentActivity, not a PaymentActivity. A PaymentConfirmation object is available for a PaymentActivity, not a PayPalAuthorization object.
I have found some really good example code for PayPal integration here, which may be helpful to someone else: https://www.csharpcodi.com/vs2/?source=176/PayPal.Forms/MobileApps/PayPal.Forms/PayPalAndroidTest/PayPalManager.cs

Watch Face Complication chooser never showed

I'm trying to implement complication support for my watch. Here's my AndroidManifest.

</intent-filter>
</activity>
</application>
</manifest>
I have a watch face service and a config activity. When I use ComplicationHelperActivity to createProviderChooserHelperIntent from the config activity I always get result cancelled in the onActivityResult. Here's how I start chooser activity and listen for the result
#Override
public void onClick(WearableListView.ViewHolder viewHolder) {
if (Log.isLoggable(TAG, Log.DEBUG)) {
Log.d(TAG, "onClick()");
}
Integer tag = (Integer) viewHolder.itemView.getTag();
ComplicationItem complicationItem = mAdapter.getItem(tag);
startActivityForResult(ComplicationHelperActivity.createProviderChooserHelperIntent(
getApplicationContext(),
complicationItem.watchFace,
complicationItem.complicationId,
complicationItem.supportedTypes),
PROVIDER_CHOOSER_REQUEST_CODE);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PROVIDER_CHOOSER_REQUEST_CODE
&& resultCode == RESULT_OK) {
ComplicationProviderInfo complicationProviderInfo =
data.getParcelableExtra(ProviderChooserIntent.EXTRA_PROVIDER_INFO);
Log.d(TAG, "Selected Provider: " + complicationProviderInfo);
finish();
}
}
It seems like I'm missing complication support and that's why can't choose any provider. But to test this I copied ComplicationSimpleWatchFaceService from the WatchFace sample and still don't have any result. Here's complication code from the watch face.
private static final int LEFT_DIAL_COMPLICATION = 0;
private static final int RIGHT_DIAL_COMPLICATION = 1;
public static final int[] COMPLICATION_IDS = {LEFT_DIAL_COMPLICATION, RIGHT_DIAL_COMPLICATION};
public static final int[][] COMPLICATION_SUPPORTED_TYPES = {
{ComplicationData.TYPE_SHORT_TEXT},
{ComplicationData.TYPE_SHORT_TEXT}
};
private void initializeComplication() {
if (Log.isLoggable(TAG, Log.DEBUG)) {
Log.d(TAG, "initializeComplications()");
}
mActiveComplicationDataSparseArray = new SparseArray<>(COMPLICATION_IDS.length);
mComplicationPaint = new Paint();
mComplicationPaint.setColor(Color.WHITE);
mComplicationPaint.setTextSize(COMPLICATION_TEXT_SIZE);
mComplicationPaint.setTypeface(Typeface.create(Typeface.DEFAULT, Typeface.BOLD));
mComplicationPaint.setAntiAlias(true);
setActiveComplications(COMPLICATION_IDS);
}

Make sure that you have called the ComplicationHelperActivity.createProviderChooserHelperIntent method, to obtain an intent and to start the provider chooser.
Sample code (make sure to call the getActivity() method for it to launch):
startActivityForResult(
ComplicationHelperActivity.createProviderChooserHelperIntent(
getActivity(),
watchFace,
complicationId,
ComplicationData.TYPE_LARGE_IMAGE),
PROVIDER_CHOOSER_REQUEST_CODE);
The intent can be used with either startActivity or startActivityForResult to launch the chooser.
You can followed this tutorial and see if you missed some configurations.

Android Auto app never calls onGetRoot

I'm developing an audio streaming application for Android and integrating Android Auto. I've been following these two tutorials.
Android Developer Training
PTR Android Blog
Using the Desktop Head Unit, I'm able to select my media app from the media app list, but from there a ProgressBar stays instead of giving way to the "To play something, open the menu at the top left." message seen in the Universal Music Player.
On inspection, it seems that the MediaBrowserServiceCompat's onGetRoot()is never invoked and thus never populating my MediaItemCompat into the Auto app's list.
My manifest contains the following.
<manifest package="com.app.audio"
xmlns:android="http://schemas.android.com/apk/res/android">
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

</application>
My automotive_app_desc.xml is very simple, only declaring Media.
<?xml version="1.0" encoding="utf-8"?>
<automotiveApp>
<uses name="media"/>
</automotiveApp>
My MediaService extends MediaBrowserServiceCompat. In the onCreate() I create and set my MediaSessionCompat.
#Override
public void onCreate() {
super.onCreate();
//...
mediaSession = new MediaSessionCompat(
this,
SESSION_TAG,
mediaIntentReceiver,
null
);
mediaSession.setFlags(
MediaSessionCompat.FLAG_HANDLES_MEDIA_BUTTONS |
MediaSessionCompat.FLAG_HANDLES_TRANSPORT_CONTROLS);
mediaSession.setCallback(new MediaSessionCompat.Callback() {
#Override
public void onPlay() {
super.onPlay();
play(selectedStream);
}
#Override
public void onPause() {
super.onPause();
pause();
}
#Override
public void onStop() {
super.onStop();
stop();
}
#Override
public void onSkipToNext() {
super.onSkipToNext();
playNextStation();
}
#Override
public void onSkipToPrevious() {
super.onSkipToPrevious();
playPreviousStation();
}
});
mediaSession.setActive(true);
setSessionToken(mediaSession.getSessionToken());
updatePlaybackState(ACTION_STOP);
}
Finally, the two overridden methods from MediaBrowserServiceCompat, of which neither is ever called.
#Nullable
#Override
public BrowserRoot onGetRoot(#NonNull String clientPackageName, int clientUid, #Nullable Bundle rootHints) {
return new BrowserRoot(ROOT_ID, null);
}
#Override
public void onLoadChildren(#NonNull String parentId, #NonNull Result<List<MediaBrowserCompat.MediaItem>> result) {
List<MediaBrowserCompat.MediaItem> items = getMediaItemsById(parentId);
if (items != null) {
result.sendResult(items);
}
}
As far as I can tell, that's everything required to get an Android Auto started, yet when I open the app on my desktop head unit, there is only a ProgressBar greeting me, and when I open the off-screen nav drawer, there's another one. I haven't heard of that state in any material I've read. Is there something I missed?

Ultimately, the issue didn't have anything to do with what I described. The aforementioned MediaService also does other tasks that require a custom Binder. This custom Binder didn't call the onGetRoot() needed for the Head Unit. As a solution, I check the Intent action and return super.onBind() when it's from the MediaBrowserServiceCompat.
#Override
public IBinder onBind(Intent intent) {
if (SERVICE_INTERFACE.equals(intent.getAction())) {
return super.onBind(intent);
}
return new MediaBinder();
}
The SERVICE_INTERFACE is a constant in MediaBrowserServiceCompat.

I'm developing an Android auto but I have some problems in this part of my code, in Onbind method of the service:
public IBinder onBind(Intent arg0) {
Log.i("TAG", "OnBind");
// TODO Auto-generated method stub
if (SERVICE_INTERFACE.equals(arg0.getAction())) {
Log.i("TAG", "SERVICE_INTERFACE");
registerReceiver(receiver, filter);
return super.onBind(arg0);
} else {
Log.i("Musica Service", "musicBind");
return musicBind;}
}
I have other activities bound with my service through a musicBind IBinder, but on the other hand I have set all things to connect my app in Android auto interface but after close my app after disconnect the device from the android auto I can't stop my mediabrowserservice compat. I think it's due to this SERVICE_INTERFACE keeps binded the service. How can I stop or destroy this from the same servicemediabrowserservicecompat?

Referral linking in Android like mCent application

I have to implement the referral linking functionality in my application like mCent application. For that I have done the following lines of code.
My application Manifest file. In the <application >..... </application> , I have done some entries for it.
<service android:name="com.google.android.gms.analytics.CampaignTrackingService" />
<receiver
android:name=".receivers.InstallReceiver"
android:exported="true" >
<intent-filter>
<action android:name="com.android.vending.INSTALL_REFERRER" />
</intent-filter>
</receiver>
And My BrodcastRecevier class is as follow , please check it.
public class InstallReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
String rawReferrer = intent.getStringExtra("referrer");
if (rawReferrer != null) {
trackReferrerAttributes(rawReferrer, context);
}
}
private void trackReferrerAttributes(String rawReferrer, Context context) {
String referrer = "";
try {
referrer = URLDecoder.decode(rawReferrer, "UTF-8");
} catch (UnsupportedEncodingException e) {
return;
}
if (Strings.isNullOrEmpty(referrer)) {
return;
}
Uri uri = Uri.parse('?' + referrer); // appends ? for Uri to pickup query string
String memberCode;
try {
referringMember = uri.getQueryParameter("mcode");
} catch (UnsupportedOperationException e) {
return;
}
SharedPreferences.Editor editor = context.getSharedPreferences(
BuildConfig.PACKAGE_NAME, Context.MODE_PRIVATE).edit();
if (!Strings.isNullOrEmpty(memberCode)) {
editor.putString(Constants.REFERRER_CODE, memberCode);
}
String referralMedium = uri.getQueryParameter("tc");
if (!Strings.isNullOrEmpty(referralMedium)) {
editor.putString("referral_medium", referralMedium);
}
editor.apply();
}
}
But i am not receiving any referral from the above code...
I have created the refferal link like this
https://play.google.com/store/apps/details?id=tv.CaseGaurd&referrer=ravindrakushwaha
Is there is any error in my referral link above OR friends , what am i doing wrong in my BroadcastRecevier class or in Manifest file

From this documentation I found that the action filter is (in manifest):
<!-- Used for install referrer tracking-->
<receiver android:name="YOUR_RECEIVER"
android:exported="true">
<intent-filter>
<action android:name="com.android.vending.INSTALL_REFERRER" />
</intent-filter>
</receiver>
Also be sure that your Receiver is in that real package ".receivers.InstallReceiver", but package com.example.app.receivers;... is your package really com.example.app?
(I considered you to be using the Google Play Store app)... also, about your downvotes, this is likely to bad wording on your question, or that you are not showing effort about your question, finally, note that this is a "free to use community forum", and that people are random...
Finally, put a breakpoint in the Receiver, send a broadcast (using adb for instance), and test that you are really not getting the broadcast.
