Answer 1

越界访问！检测一下MainActivity中，有没有空的 数组或集合，如果为空不能读取元素。

Answer 2

检查oncreate中是否有array或list越界操作。

Answer 3

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
// getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
// WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
MyApplication.getInstance().addActivity(this);
context = this;
inflater = LayoutInflater.from(this);
// 获取上次退出时的播放位置
initView();
startService(new Intent(context, MusicPlayerService.class));
// 启动service
Intent intent = new Intent(this, DownloadService.class);
startService(intent);
this.getApplicationContext()
.bindService(intent, conn, BIND_AUTO_CREATE);
// 创建音乐目录
if (Environment.getExternalStorageState().equals(
Environment.MEDIA_MOUNTED)) {
File root = Environment.getExternalStorageDirectory();
dir = new File(root, "TMusic");
if (!dir.exists()) {
dir.mkdir();
}
}
myReciver = new MusicReciver();
reciver = new refreshReciver();
groupDao = new MusicGroupDao(context);
}

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
// getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
// WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
MyApplication.getInstance().addActivity(this);
context = this;
inflater = LayoutInflater.from(this);
// 获取上次退出时的播放位置
initView();
startService(new Intent(context, MusicPlayerService.class));
// 启动service
Intent intent = new Intent(this, DownloadService.class);
startService(intent);
this.getApplicationContext()
.bindService(intent, conn, BIND_AUTO_CREATE);
// 创建音乐目录
if (Environment.getExternalStorageState().equals(
Environment.MEDIA_MOUNTED)) {
File root = Environment.getExternalStorageDirectory();
dir = new File(root, "TMusic");
if (!dir.exists()) {
dir.mkdir();
}
}
myReciver = new MusicReciver();
reciver = new refreshReciver();
groupDao = new MusicGroupDao(context);
}

initView();中做了什么
