It works the way i want to but if i click on submit without entering anything it crashes.

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button addBtn = (Button) findViewById(R.id.addBtn);
        addBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                EditText amoutGiven = (EditText) findViewById(R.id.amountG);
                EditText manyPeople = (EditText) findViewById(R.id.mPeople);
                EditText moenyGiven = (EditText) findViewById(R.id.moneyG);

                android.view.inputmethod.InputMethodManager imm = (android.view.inputmethod.InputMethodManager)getSystemService(INPUT_METHOD_SERVICE);
                imm.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);

                if (amoutGiven.getText().length()==0){
                    amoutGiven.setError("This field is required");
                }

                if (manyPeople.getText().length()==0){
                    manyPeople.setError("This field is required");
                }

                if (moenyGiven.getText().length()==0){
                    moenyGiven.setError("This field is required");
                }

                int num1 = Integer.parseInt(amoutGiven.getText().toString());

                int total = num1 * num2;
                int change = num3 - total;

                changeTxt.setVisibility((changeTxt.getVisibility() == View.VISIBLE)
                        ? View.INVISIBLE : View.VISIBLE);

                if (change < 0 ){
                    changeTxt.setText("Your numbers dont add up");
                    tryBtn.setVisibility((tryBtn.getVisibility() == View.VISIBLE)
                            ? View.INVISIBLE : View.VISIBLE);
                    tryBtn.setOnClickListener(new View.OnClickListener() {

                        }
                    });

I found that most released apps(including system apps) can be debugged on the emulator by the way following:
1. install the app on the emulator, and launch it
2. run adb shell ps to get the pid of the app
3. run adb jdwp, if you find the pid in the output, then you can attach to the app by running
adb forward tcp:1234 jdwp:$pid_you_find and jdb -connect com.sun.jdi.SocketAttach:hostname=localhost,port=1234
4. you can use commands such as "classes" to see the classes of the app, even "stop" to set breakpoint and "eval" to run many functions and see the members of the objects.
I have 2 questions:
1. Why these tricks fail on the phones? What's the difference between the rom of emulator and phones?
2. How to avoid my app being debugged through such way?

I found a config value in packages/app/Bluetooth/res/values/config.xml and a hide class

  • false
  • android.bluetooth.BluetoothHeadsetClient, this provides HFP client API, such as dial, accept call.

I set profile_supported_hfpclient to true, and remake and flash the system. I write a test app to using BluetoothHeadsetClient API, and it can dial and accept call. However, the voice is not working when calling. The speaker doesn't make sound, and the voice received by mic isn't transferred by Bluetooth SCO.

So does android support HFP client fully? How can I make voice works well
