I'm trying to make a simple app that'll lock the screen of the device when an incoming call is accepted. For this, I'm made a custom device admin with the help of this tutorial. But, when I click the "Enable" button in my app, the Device Policy Manager activity does not open at all! And I get output in the logcat window that says that my ComponentName is invalid. However, I do not find any problems in my project what so ever!

componentName = new ComponentName(this, LockAdmin.class);
}

Intent intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);
intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN, componentName);
intent.putExtra(DevicePolicyManager.EXTRA_ADD_EXPLANATION, "Lock Admin by Swap");
startActivityForResult(intent, 1);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1 && resultCode == Activity.RESULT_OK) {
Toast.makeText(getBaseContext(), "Lock Admin by Swap added successfully", Toast.LENGTH_SHORT).show();

P.s. - I tested out the app on two different devices on based on AOSP KitKat(4.4.2) and another one CyanogenOS 12.0(5.0.2), it didn't work on either of them.

I wanted my Application to send notification everyday to the user, following this link and doing everything as described. The app doesn't send notifications. The buildLocalNotification function is being triggered every 60 seconds, but no Notification is displayed. I kept an Interval of 2000 ms but android changed it to 60 Seconds.
Logcat Message: Suspiciously short interval 2000 millis; expanding to 60 seconds Every 60 seconds the notification function is triggered.
This is my

if (intent.getAction().equals("android.intent.action.BOOT_COMPLETED")) {
//only enabling one type of notifications for demo purposes

}
}
}
This is the code that turn notification on and off:
swnotf.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean b)
{
if(b)
{
Log.d("DEBUG", "onCheckedChanged: "+ "ON");

else
{

NotificationHelper.cancelAlarmElapsed();
NotificationHelper.disableBootReceiver(getContext());
}
}
});
Please I have already spent THREE days trying other solutions and fixing this. I don't want to spend more time on this. Any help would be Appreciated.
Thank you.
I am trying to create a media player without MediaPlayer class, just a very basic VideoView which selects a file from device and plays it. But I am receiving an error
Can't play this video.
Here's my code:
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.content.pm.ActivityInfo;
import android.net.Uri;
import android.os.Bundle;
import android.widget.Toast;
import android.widget.VideoView;
public class PlayerActivity extends AppCompatActivity {
VideoView videoPlayer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
videoPlayer = findViewById(R.id.videoView);
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("*/*");
startActivityForResult(intent, 7);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case 7:
if (resultCode == RESULT_OK) {
String PathHolder = data.getData().getPath();
Toast.makeText(this, PathHolder, Toast.LENGTH_SHORT).show();
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
videoPlayer.setVideoURI(Uri.parse(PathHolder));
videoPlayer.requestFocus();
videoPlayer.start();
}
}
}
}
XML file:

I am not used to content provider.Please help.
I didn't understand what was the problem.But it was solved when I changed onActivityResult to
switch (requestCode) {
case 7:
if (resultCode == RESULT_OK) {
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
videoPlayer.setVideoURI(data.getData());
videoPlayer.requestFocus();
videoPlayer.start();
}
}
Try to set orientation with object of video player
case 7:
if (resultCode == RESULT_OK) {
String PathHolder = data.getData().getPath();
Toast.makeText(this, PathHolder, Toast.LENGTH_SHORT).show();
videoPlayer.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
videoPlayer.setVideoURI(Uri.parse(PathHolder));
videoPlayer.requestFocus();
videoPlayer.start();
}
I have an issue with my app that i cant solve. The app takes the input(reminder) from a user and then sets it as a notification. The user can create as many notifications as he/she likes. I want the user to click the notification and get taken to a new activity(Reminder), so he/she can see the reminder in a TextView. So i have an activity(SetReminder), which let the user put his data in a text editor.Then i save his data in a hashMap. The int is the id of user's string data. Then i have a class (AlarmReceiver) which extends BroacastReceiver and generates the notification.In this class i have an id for each notification,which matches the hashMap's int from the SetReminder activity. That way i was expecting that the user would see the data of each notification.But that's doesn't happen. I have multiple Notifications(i want that), but the user sees the data of the last notification, no matter which notifications selects. I am posting the code from the three activities.
Thanks in advance.

dont use static id,in your code id is always 0. you can check it using Log!
use another way for produce different ids.
when you add notification with same id, the new notification will replace with last notification. use random integer for id

There is no activity on your device that supports ACTION_VIEW of a content Uri for whatever MIME type that content is. There is no requirement for an Android device to have an ACTION_VIEW activity for every possible piece of content.
I am learning how to build home screen widget in Android. This code is for an app widget to toggle RingerMode from NORMAL to SILENT and vice-versa.
This works fine but I need a full in-sight of logical flow (i.e which gets initiated when, goes where, does what, dies when) of all the intents in this.
Please help me understand this topic clearer.

still not sure on what are u asking, but I'll try to answer, if not what u want, please explain in a different way.
Intent are usually started immediatly. You create an Intent can start it by calling startService or startActivity, so for example:
context.startService(new Intent(context, ToggleService.class));
on both times you wrote the above code, the service ToggleService is immediatly started.
PendingIntent on the other hand are saved to be started at later time, so for example
updateViews.setOnClickPendingIntent(R.id.phoneState, pi);
on the above line, the AppWidget Broadcast is started when the user clicks on R.id.phoneState in your HomeScreen AppWidget.
Each PendingIntent is stored in the system with a certain ID, this ID is the requestCode parameter (you used zero on your code)... that means, that if you create a different PendingIntent with the same ID it will override it, meaning a different action will be started when the user clicks on R.id.phoneState
