广播接收器在某些设备中使应用程序崩溃

Posted 2021-04-08

我有一个android应用程序，我正在使用广播接收器和报警管理器设置一些任务。这是一个非常简单的应用程序，如提醒，用户创建提醒，系统将唤醒用户吐司和哔哔声。

在我的活动中，我按如下方式设置了任务：

Bundle bundle = new Bundle();
MyAlarm alarm = new MyAlarm(MainActivity.this, bundle, sec);    

我的警报类如下：

public class MyAlarm extends BroadcastReceiver {
private final String REMINDER_BUNDLE = "MyReminderBundle"; 
public MyAlarm(){ }

public MyAlarm(Context context, Bundle extras, int timeoutInSeconds){
     AlarmManager alarmMgr = 
         (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
     Intent intent = new Intent(context, MyAlarm.class);
             intent.putExtra(REMINDER_BUNDLE, extras);
     PendingIntent pendingIntent =
         PendingIntent.getBroadcast(context, 0, intent, 
         PendingIntent.FLAG_UPDATE_CURRENT);
     Calendar time = Calendar.getInstance();
     time.setTimeInMillis(System.currentTimeMillis());
     time.add(Calendar.SECOND, timeoutInSeconds);
     alarmMgr.set(AlarmManager.RTC_WAKEUP, time.getTimeInMillis(),
                  pendingIntent);
 }

 public void onReceive(Context context, Intent intent) {
 Toast.makeText(context, "Received", Toast.LENGTH_LONG).show();
 try{
    playSound(context);
    }
    catch(Exception e)
    {
    e.printStackTrace();
    }
}

我的playound代码如下：

public void playSound(Context context) throws IllegalArgumentException, SecurityException, IllegalStateException,
  IOException {
Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
MediaPlayer mMediaPlayer = new MediaPlayer();
mMediaPlayer.setDataSource(context, soundUri);
final AudioManager audioManager = (AudioManager)  context.getSystemService(Context.AUDIO_SERVICE);
if (audioManager.getStreamVolume(AudioManager.STREAM_ALARM) != 0) {
  mMediaPlayer.setAudiostreamType(AudioManager.STREAM_ALARM);
  mMediaPlayer.setLooping(false);
  mMediaPlayer.prepare();
  mMediaPlayer.start();
 }
}

我的问题是它在仿真器和其他设备上运行良好，但它不适用于三星和Micromax设备。

getList()方法：

public String getList(Context context,Date c)
 {
     String check = "Default";
     SQLiteDatabase sampleDB= context.openOrCreateDatabase(SAMPLE_DB_NAME, Context.MODE_PRIVATE, null);
 Cursor cc = sampleDB.rawQuery("SELECT * FROM " + SAMPLE_TABLE_NAME, null);  
 Log.d("Sent date is :-",c.toString());
 if(cc != null)
     if(cc.moveToFirst())
     do
     {
         Log.d("in do", "Success");
         Date v = new Date(cc.getString(2).trim());  
         if(v.getTime() - c.getTime() >= 0 && v.getTime() - c.getTime() <=1000){   
             Log.d("inside first if", "Success");
            Log.d("Number is",cc.getString(1));
            if(cc.getString(3).equals("ON")){
                 Log.d("inside second if", "Success");
                  try{
                         playSound(context);
                         }
                         catch(Exception e)
                         {

                         }
            Toast.makeText(context, "A call is scheduled for" + cc.getString(1)+".and it is about to be triggered", Toast.LENGTH_LONG).show();
            check = cc.getString(1);
            break;
            }

         }

         }while(cc.moveToNext());

     sampleDB.close();
     return check;

 }

下面是我的错误logcat：

答案

代替

Date v = new Date(cc.getString(2).trim());  

尝试这样的事情：

 SimpleDateFormat parserSDF=new SimpleDateFormat("EEE MMM d HH:mm:ss zzz yyyy");
        String dateInString = "7-Jun-2013";

        try {

            Date v= formatter.parse(dateInString);


        } catch (ParseException e) {
            e.printStackTrace();
        }

确保您的字符串采用SimpleDateFormat中提到的有效格式。

签出已更改的SimpleDateFormat

SimpleDateFormat parserSDF=new SimpleDateFormat("EEE MMM d HH:mm:ss zzz yyyy");

另一答案

请更换你的线路

Date v = new Date(cc.getString(2).trim());

同

Date v = SimpleDateFormat.parse(cc.getString(2).trim()))
