I want to change the brightness using seekBar it changes but the notification brightness bar progress is not the same as the progress value.
public class MainActivity extends AppCompatActivity {
private SeekBar seekBright;
private TextView txtProgress;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
seekBright=findViewById(R.id.seekBright);
txtProgress=findViewById(R.id.txtProgress);
if(Build.VERSION.SDK_INT> Build.VERSION_CODES.M) {
boolean canWriteSettings = Settings.System.canWrite(this);
if (!canWriteSettings) {
Intent intent = new Intent(Settings.ACTION_MANAGE_WRITE_SETTINGS);
startActivity(intent);
}
}
seekBright.setMax(255);
seekBright.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int i, boolean b) {
setScreenBrightness(MainActivity.this,i);
txtProgress.setText(i+"/"+seekBar.getMax
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
// finally use the below method to set the brightness
new LoadApplications().execute();
}
public void setScreenBrightness(Context mContext, int brightnessValue){
// Make sure brightness value between 0 to 255
if(brightnessValue >= 0 && brightnessValue <= 255){
Settings.System.putInt(
mContext.getContentResolver(),
Settings.System.SCREEN_BRIGHTNESS,
brightnessValue
);
}
}
}
This Output of my code
When set to 0 progress is displayed anywhere.
when set to 1 it displays proper
** Screenshot emulator version I SDK-33**
I had this problem too. I did a lot of searches and built it together:

alertDialog.show();
alertDialog.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(getResources().getColor(R.color.black));
alertDialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(getResources().getColor(R.color.black));
}
}
}
At the end of the code is AlertDialog which checks for permission to write settings.
Hope it helps 😁👍

Currently, I'm developing a media player and I need seekBar to work together, at the moment, it's everything okay! but, when I touch at determinated position of the seekbar, the mediaplayer must follow and set the song to this determinated position, but the song and seekBar back to the start and I don't know why it's happening.
MainActivity.java
public class MainActivity extends AppCompatActivity {
private Handler mHandler = new Handler();
public TextView song_detail;
public TextView time1;
public TextView time2;
private String player_status = "playing";
private ImageButton player_img;
public static SeekBar seekBar;
private static MediaPlayer mediaPlayer;
#SuppressLint("RestrictedApi")
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
song_detail = findViewById(R.id.song_detail);
song_detail.setVisibility(View.GONE);
time1 = findViewById(R.id.time_1);
time2 = findViewById(R.id.time_2);
seekBar = findViewById(R.id.seekBar);
final Runnable mRunnable = new Runnable() {
#Override
public void run() {
if(mediaPlayer != null){
int CurrentPosition = mediaPlayer.getCurrentPosition();
String m_1;
String s_1;
seekBar.setProgress(CurrentPosition/1000);
final int minutes_1 = (CurrentPosition/1000)/60;
final int seconds_1 = ((CurrentPosition/1000)%60);
if (minutes_1 < 10) {
m_1 = "0" + minutes_1;
} else {
m_1 = "" + minutes_1;
}
if (seconds_1 < 10) {
s_1 = "0" + seconds_1;
} else {
s_1 = "" + seconds_1;
}
time1.setText(m_1 + ":" + s_1);
int Duration = mediaPlayer.getDuration();
String m_2;
String s_2;
final int minutes_2 = (Duration/1000)/60;
final int seconds_2 = ((Duration/1000)%60);

if (seconds_2 < 10) {
s_2 = "0" + seconds_2;
} else {
s_2 = "" + seconds_2;
}
time2.setText(m_2 + ":" + s_2);
}
mHandler.postDelayed(this, 1000);
}
};
mRunnable.run();
seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
if(mediaPlayer != null && fromUser){
Toast.makeText(getApplicationContext(), String.valueOf(progress), Toast.LENGTH_LONG).show();

seekBar.setProgress(progress);
}
}

});
}
public void initAudio(final Context context, final String url) {

mediaPlayer = MediaPlayer.create(context, Uri.parse(url));
}
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
//Toast.makeText(context, "TEST", Toast.LENGTH_LONG).show();
killMediaPlayer();
}
});
seekBar.setMax(mediaPlayer.getDuration()/1000);
mediaPlayer.start();
}
public void killMediaPlayer() {
if (mediaPlayer != null) {
try {
mediaPlayer.reset();
mediaPlayer.release();
mediaPlayer = null;
} catch (Exception e) {
e.printStackTrace();
}
}
}
public static void pauseAudio() {
if (!(mediaPlayer == null)) {
mediaPlayer.pause();
}
}
public static void startAudio() {
if (!(mediaPlayer == null)) {
mediaPlayer.start();
}
}
}
This is the part of code that I'm using to work with mediaPlayer and seekBar
seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
if(mediaPlayer != null && fromUser){
Toast.makeText(getApplicationContext(), String.valueOf(progress), Toast.LENGTH_LONG).show();
mediaPlayer.seekTo(progress);
seekBar.setProgress(progress);
}
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) { }
#Override
public void onStopTrackingTouch(SeekBar seekBar) { }
});
}
But as I have said, instead of mediaPlayer seek and continue the audio from the position that I've clicked, the audio simply back to the start. What I'm doing wrong?
Thank you.
The max value for progress is 100. The seekTo function takes time in milliseconds. This is why it seeks to the start (almost) of the audio.
So instead of mediaPlayer.seekTo(progress);, you need to do:
long newTime = (progress/100.0) * total_audio_duration_in_millisecond;
mediaPlayer.seekTo(newTime);
i want to do something like parallax, so I use the G Sensor

My problem is there's only old tutorials I guess and
google something changed?

When using this code the image moves away. I tried the most of answer from this site but nothings working.
On the top you can see the g sensor x y by holding the smartphone normaly.
Is it possible that my G Sensor not working correctly?
Thanks
I am trying to create a flashlight app with a strobe effect. My goal is that I can turn ON/OFF the flashlight with a switch Btn and increase the strobe frequency with a seekbar. If the seekbar value is 0 and the switch Btn is ON the flashlight should be ON (without any strobe). But right now it is still blinking (strobe effect ON) if the seekbar value is 0. Do you know how I can change that?
Here is some of the code which I think is important (I really can't find the part which keeps the stobe effect still on:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mySwitch = (Switch) findViewById(R.id.mySwitch);
//listener to check changes in state
mySwitch.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
turnOnOff(isChecked);
}
});
skBar = (SeekBar) findViewById(R.id.seekBar);
skBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
freq = progress;
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
}
#Override
protected void onResume() {
super.onResume();
try {
cam = Camera.open();
camParams = cam.getParameters();
cam.startPreview();
hasCam = true;
}catch(Exception e){
}
}
private void turnOnOff(boolean on){
if(on) {
if(freq != 0){
sr = new StroboRunner();
t = new Thread(sr);
t.start();
return;
}else{
camParams.setFlashMode(Parameters.FLASH_MODE_TORCH);
}
}else if(!on){
if(t != null){
sr.stopRunning = true;
t =null;
return;
}else{
camParams.setFlashMode(Parameters.FLASH_MODE_OFF);
}
}
cam.setParameters(camParams);
cam.startPreview();
}
private class StroboRunner implements Runnable {
boolean stopRunning = false;
#Override
public void run() {
Camera.Parameters paramsOn = cam.getParameters();
Camera.Parameters paramsOff = camParams;
paramsOn.setFlashMode(Parameters.FLASH_MODE_TORCH);
paramsOff.setFlashMode(Parameters.FLASH_MODE_OFF);
try {
while (!stopRunning) {
cam.setParameters(paramsOn);
cam.startPreview();
Thread.sleep(100 - freq);
cam.setParameters(paramsOff);
cam.startPreview();
Thread.sleep(100 - freq);
}
}catch(Exception e){

So im trying to make something like this https://play.google.com/store/apps/details?id=pt.bbarao.nightmode .

However if I write

at the place of TurnoffStrobe in the oncreate (not onBackPressed), its working. What can I do to have runner.requeststop working outside onCreate.?
Try
your_thread.isInterrupted(); inside onBackpress()
