SOLVED IT:
It was a problem of my Phone after resetting it everything worked.
Thanks to everybody that tried to help me.
I write a app in Android Studio and tested it on my device today I uninstalled it and tried to run it with Android Studio. But the app wont start and Android Studio generates the following error:
$ adb shell am start -n "de.clashbestie.pccontrol/de.clashbestie.pccontrol.activities.ConnectActivity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER
Error while executing: am start -n "de.clashbestie.pccontrol/de.clashbestie.pccontrol.activities.ConnectActivity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER
Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=de.clashbestie.pccontrol/.activities.ConnectActivity }
Error type 3
Error: Activity class {de.clashbestie.pccontrol/de.clashbestie.pccontrol.activities.ConnectActivity} does not exist.
Error while Launching activity
And a screenshot too
Yes I see the "does not exist" and yeah this is the problem, the app gets not installed, but as seeable in the screenshot Android Studio say "Install succesfully finished".
I tried clean & rebuild restarted Android Studio, my PC, and My Device. Anybody knows what I can do else?
Btw. In emulator the app gets intalled.
Here is my mainfest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

ConnectActivity.java: (Removed Imports to short it)
package de.clashbestie.pccontrol.activities;
public class ConnectActivity extends AppCompatActivity {
private static ConnectActivity instance;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
instance = this;
}
public void connect(View v) {
findViewById(R.id.ip).clearFocus();
findViewById(R.id.port).clearFocus();
Button button = (Button) findViewById(R.id.connect);
if (button.getText().equals(getString(R.string.button_connecting))) {
Snackbar.make(instance.findViewById(R.id.connect), "Already connecting", Snackbar.LENGTH_SHORT).show();
} else {
button.setText(R.string.button_connecting);
String ip = ((EditText) findViewById(R.id.ip)).getText().toString();
String port = ((EditText) findViewById(R.id.port)).getText().toString();
((InputMethodManager) this.getSystemService(Activity.INPUT_METHOD_SERVICE)).hideSoftInputFromWindow(findViewById(R.id.connect).getWindowToken(), 0);
new ConnectorThread(ip, port).start();
}
}
public static void launchControlActivity(Socket socket) {
Button button = (Button) instance.findViewById(R.id.connect);
button.setText(R.string.button_connect);
try {
socket.close();
} catch (IOException e) {
e.printStackTrace();
}
instance.getApplicationContext().startActivity(new Intent(instance, ControlActivity.class));
}
public static void showConnectError(String text) {
Button button = (Button) instance.findViewById(R.id.connect);
button.setText(R.string.button_connect);
Snackbar.make(instance.findViewById(R.id.connect), text, Snackbar.LENGTH_LONG).show();
}
}
