无论我做什么，我的所有应用程序都会强行关闭

标签： java android eclipse forceclose

我是一名试图启动的新编码员。我有一个奇怪的问题。我一直在努力的所有应用程序（包括hello world / myfirstapp演示）强制关闭。每次我将它们加载到真实设备上或从模拟器运行它们。当我尝试执行某些功能时，它们会强制关闭。没有突出显示的错误。更何况，eclipse不会在任何现实世界的设备上安装我的应用程序（我手动完成）。我的一个应用程序播放来自应用内资源的音频文件;在这个应用程序中我认为它强制关闭start（）播放音频的调用。 （这个应用程序不完整，但仍然没有错误，应该有效）。另一个只是让手机静音一段时间;在这里，我认为它在设置警报的呼叫后关闭。这是我的代码，请帮帮我。如果您发现任何错误，请告诉我。 （也是的，我做了我的研究，无法找到任何东西。）我认为它可能是eclipse的一个问题，或者一个简单的语法/ java练习我还没有完成，我不知道。我是新人，愿意向有经验的人学习。

所以这是我的媒体应用程序的主要活动。

    package com.STI.stockhollywoodsoundeffects;

import android.app.Activity;
import android.media.MediaPlayer;
import android.media.MediaPlayer.OnCompletionListener;
import android.os.Bundle;
import android.view.View;


public class MainActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

    }

    public void testsound (View view){
    MediaPlayer mediaPlayer = MediaPlayer.create(this, R.raw.tooclose);
    mediaPlayer.start(); 
    mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
        public void onCompletion(MediaPlayer mediaPlayer) {
            mediaPlayer.release();
            mediaPlayer = null;


            }
        });


    }
}

如果有人想看到任何其他文件，请告诉我，我会发布。

这是＆＃34;定时铃声消音器的主要活动＆＃34;应用

package com.STI.timedringtonesilencer;        

import android.os.Bundle;
import android.view.View;
import android.app.Activity;
import android.app.DialogFragment;

public class MainActivity extends Activity {

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

    }

    public void startpicker(View v) {
        DialogFragment newFragment = new Fragment1();
        newFragment.show(getFragmentManager(), "timePicker");
    }

    }

最后我的这个课程的片段（可能问题在这里，但我再也不知道了）

 package com.STI.timedringtonesilencer;

 import java.util.Calendar;

 import android.annotation.SuppressLint;
 import android.app.AlarmManager;
 import android.app.Dialog;
 import android.app.DialogFragment;
 import android.app.PendingIntent;
 import android.app.TimePickerDialog;
 import android.app.TimePickerDialog.OnTimeSetListener;
 import android.content.Context;
 import android.content.Intent;
 import android.media.AudioManager;
 import android.os.Bundle;
 import android.os.SystemClock;
 import android.text.format.DateFormat;
 import android.widget.TimePicker;

 @SuppressLint("NewApi")
 public class Fragment1 extends DialogFragment
 implements TimePickerDialog.OnTimeSetListener {
     public static final int REQUEST_CODE = 0;




     @Override
     public Dialog onCreateDialog(Bundle savedInstanceState) {
         final Calendar C = Calendar.getInstance();
         int hourofday2 = C.get(Calendar.HOUR_OF_DAY);
         int minute2 = C.get(Calendar.MINUTE);


         return new TimePickerDialog(getActivity(), (OnTimeSetListener) this,          hourofday2, minute2, 
            DateFormat.is24HourFormat(getActivity()));
}

public void onTimeSet(TimePicker view, int hourofday2, int minute2 ) {
    final Calendar C = Calendar.getInstance();
    int hourofday1 = C.get(Calendar.HOUR_OF_DAY);
    int minute1 = C.get(Calendar.MINUTE);
    int numominutes = minute2 - minute1;
    int numohours = hourofday2 - hourofday1;
    int numohours1 = numohours * 3600;
    int numominutes1 = numominutes * 60;
    int seconds = numohours1 + numominutes1;
    int miliseconds = seconds * 1000;
    int alarmType = AlarmManager.ELAPSED_REALTIME_WAKEUP;
    Intent intent = new Intent(getActivity(), RingVolumeActivity.class);
    intent.setAction(Intent.ACTION_MAIN);
    intent.setFlags(Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);
    PendingIntent pendingIntent = PendingIntent.getActivity(getActivity(), REQUEST_CODE,
            intent, 0);
    AudioManager audiomanager = (AudioManager)
    getActivity().getSystemService(Context.AUDIO_SERVICE);
    audiomanager.setRingerMode(AudioManager.RINGER_MODE_SILENT);
    AlarmManager alarmManager = (AlarmManager)
            getActivity().getSystemService(Context.ALARM_SERVICE);
    alarmManager.setExact(alarmType, SystemClock.elapsedRealtime() + miliseconds, pendingIntent);
