My app crashing when I try to toggle phone modes. For example when I'm in ring mode end I try to switch on silent is crashing, but when I try to toggle vibrate is working fine. Exactly the same thing is happening when I try to change from vibrate to ring. Check status is working fine, there is not crash.
Here is the logcat line:
at com.example.lab3_1.MainActivity.onSilent(MainActivity.java:56)
That involved the code line:
myAudioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT);
Here is the main:

I'm new to Android App development (on android studio) and to start off I'm creating a simple 'bonk' soundboard app, and testing it using the Pixel 2 android emulator. The goal of the app is to play the bonk noise whenever someone presses the BONK button on my main screen. I also wanted to implement a seekbar that adjusts the volume when you slide it. To do this I followed a simple implementation I found here on StackOverflow (shown below).
Even though the rest of my app works fine, for some reason my volume won't adjust whenever I slide the seekbar. Here is my code:
MainActivity.java
package com.example.bonk;
import androidx.appcompat.app.AppCompatActivity;
import android.media.AudioManager;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.SeekBar;
public class MainActivity extends AppCompatActivity {
Button bonkButton;
SeekBar volumeSeekBar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
bonkButton = (Button)findViewById(R.id.bonkButton);
volumeSeekBar = (SeekBar)findViewById(R.id.volumeSeekBar);
final MediaPlayer mp = MediaPlayer.create(this, R.raw.bonksound);
bonkButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mp.start();
}
});
}
}
Volumizer.java
package com.example.bonk;
import android.app.Activity;
import android.content.Context;
import android.media.AudioManager;
import android.os.Bundle;
import android.widget.SeekBar;
import android.widget.SeekBar.OnSeekBarChangeListener;
public class Volumizer extends Activity {
//Called when the activity is first created.
private SeekBar volumeSeekbar = null;
private AudioManager audioManager = null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setVolumeControlStream(AudioManager.STREAM_MUSIC);
setContentView(R.layout.activity_main);
initControls();
}
private void initControls() {
try {
volumeSeekbar = findViewById(R.id.volumeSeekBar);
audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
volumeSeekbar.setMax(audioManager
.getStreamMaxVolume(AudioManager.STREAM_MUSIC));
volumeSeekbar.setProgress(audioManager
.getStreamVolume(AudioManager.STREAM_MUSIC));
volumeSeekbar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
#Override
public void onStopTrackingTouch(SeekBar arg0) {
}
#Override
public void onStartTrackingTouch(SeekBar arg0) {
}
#Override
public void onProgressChanged(SeekBar arg0, int progress, boolean arg2) {
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC,
progress, 0);
}
});
} catch (Exception e) {
e.printStackTrace();
}
}
}

Please let me know if you have any ideas as of what I may be doing wrong. Thank you!
I was able to solve the problem by moving my initControls() function definition into my MainActivity.java class and calling it onCreate.
I'm a beginner programmer and I'm working on an app where I want to have a Settings activity with 2 switch buttons (one to turn on/off notifications in status bar and one to turn on/off notification sound).Yesterday everything went fine with the compiling but today suddenly I got all these errors about not resolving some methods or symbols. What happened and how can I fix it?
In particular the errors where the following:
cannot resolve method: onCreate,setContentView,getSystemService, findViewById
cannot resolve symbol: OnCheckedChangeListener, simpleswitch1, simpleswitch2, arg0, view
Override: Annotations are not allowed here

From you java you are placing methods inside other methods this is not possible in java
Also
Try setting listeners as such
// set default state on/off
simpleSwitch1.setChecked(false);
simpleSwitch2.setChecked(false);
simpleSwitch1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked){
// prepare your notification and display
}else{
// do something
}
}
});
simpleSwitch2.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked){
// prepare your notification and display
}else{
// do something
}
}
});
hope this helps, your java code was quite hard to understand.
This question already has an answer here:
Notifications don't appear
(1 answer)
Closed 2 years ago.
I'm new to programming and app development and I'm trying to develop an app that shows events and notifies the user when a new event is up.I'm trying to create a settings activity with 2 switch buttons, 1 for notifications on status bar and 1 for notification sound. When I turn on the switches, I don't get any notification nor sound.
How can I fix that?

A couple of stuff here:
For switches, you probably want OnCheckedChangeListener, not
OnClickListener.
You want to set the OnCheckedChangeListener once in your onCreate() and check for the Switch's state
inside this listener:
simpleswitch1 = (Switch) findViewById(R.id.simpleswitch1);
simpleswitch2 = (Switch) findViewById(R.id.simpleswitch2);
simpleSwitch1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked) {
// show notification
} else {
// cancel notification
}
}
});`
// Similarly for switch2`
I have a splash screen and after that my main activity starts. This works fine in portrait mode but if in case i tilt my phone in landscape mode, the main activity can be seen launching more than once after splash screen.
I tried using android:launchMode="singleInstance" but in that case i am not able to attach files in feedback alert-box.

Dont use android:launchMode="singleInstance"
Launch mode you should use "singleTask" for this .
Because singleInstance creates separate task stack for Activity and do not check activity in current Task Stack.
while "singleTask" check each time if an Activity exist in Task Stack it can not create new one.
How to get time for splashcreen?
I want to add about 15 second time? How can I integrate it into the code?
For example, to direct activity after about 15 seconds.
package com.trees.activities;
import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
public class MainSlider extends Activity{
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
SharedPreferences settings=getSharedPreferences("prefs",0);
boolean firstRun=settings.getBoolean("firstRun",false);
if(firstRun==false)//if running for first time
//Splash will load for first time
{
SharedPreferences.Editor editor=settings.edit();
editor.putBoolean("firstRun",true);
editor.commit();
Intent i=new Intent(MainSlider.this,MaterialIntro.class);
startActivity(i);
finish();
}
else
{
Intent a=new Intent(MainSlider.this,MainActivity.class);
startActivity(a);
finish();
}
}
}
HOW TO: Simple spash screen
First you need to define the spash screen in your layout.xml file
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView android:id="#+id/splashscreen" android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:src="#drawable/splash"
android:layout_gravity="center"/>
<TextView android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Hello World, splash"/>
</LinearLayout>
And your activity:
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
public class Splash extends Activity {
/** Duration of wait **/
private final int SPLASH_DISPLAY_LENGTH = 1000;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.splashscreen);
/* New Handler to start the Menu-Activity
* and close this Splash-Screen after some seconds.*/
new Handler().postDelayed(new Runnable(){
#Override
public void run() {
/* Create an Intent that will start the Menu-Activity. */
Intent mainIntent = new Intent(Splash.this,Menu.class);
Splash.this.startActivity(mainIntent);
Splash.this.finish();
}
}, SPLASH_DISPLAY_LENGTH);
}
}
