Мой код по идее рабочий но проблемы с манифестом
public class MainActivity extends AppCompatActivity {
private static final int PERMISSION_REQUEST_CODE = 200;
Button btn_click;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btn_click = findViewById(R.id.open);
btn_click.setOnClickListener(new View.OnClickListener() {
@RequiresApi(api = Build.VERSION_CODES.N)
@Override
public void onClick(View v) {
if (checkPermission()) {
Intent launcher = getApplication().getPackageManager().getLaunchIntentForPackage("com.facebook.katana");
if(launcher != null) {
startActivity(launcher);
} else {
Toast.makeText(MainActivity.this, "Failed", Toast.LENGTH_SHORT).show();
}
} else {
requestPermission();
}
}
});
}
@RequiresApi(api = Build.VERSION_CODES.N)
private boolean checkPermission() {
int result = ContextCompat.checkSelfPermission(getApplicationContext(), WRITE_EXTERNAL_STORAGE);
int result1 = ContextCompat.checkSelfPermission(getApplicationContext(), READ_EXTERNAL_STORAGE);
return result == PackageManager.PERMISSION_GRANTED && result1 == PackageManager.PERMISSION_GRANTED;
}
@RequiresApi(api = Build.VERSION_CODES.N)
private void requestPermission() {
ActivityCompat.requestPermissions(this, new String[]{WRITE_EXTERNAL_STORAGE, READ_EXTERNAL_STORAGE}, PERMISSION_REQUEST_CODE);
}
}
