android 监听SDCard安装和卸载的代码片段（测试通过）

// 监听类
private final BroadcastReceiver sdcardListener = new BroadcastReceiver() {

@Override
public void onReceive(Context context, Intent intent) {

String action = intent.getAction();
Log.d("TAG", "sdcard action:::::" + action);
if(Intent.ACTION_MEDIA_MOUNTED.equals(action)
|| Intent.ACTION_MEDIA_SCANNER_STARTED.equals(action)
|| Intent.ACTION_MEDIA_SCANNER_FINISHED.equals(action)
){
// SD卡成功挂载

} else if(Intent.ACTION_MEDIA_REMOVED.equals(action)
|| Intent.ACTION_MEDIA_UNMOUNTED.equals(action)
|| Intent.ACTION_MEDIA_BAD_REMOVAL.equals(action)
){
// SD卡挂载失败

}

}
};

// 注册监听
private void registerSDCardListener(){
IntentFilter intentFilter = new IntentFilter(Intent.ACTION_MEDIA_MOUNTED);
intentFilter.addAction(Intent.ACTION_MEDIA_SCANNER_STARTED);
intentFilter.addAction(Intent.ACTION_MEDIA_SCANNER_FINISHED);
intentFilter.addAction(Intent.ACTION_MEDIA_REMOVED);
intentFilter.addAction(Intent.ACTION_MEDIA_UNMOUNTED);
intentFilter.addAction(Intent.ACTION_MEDIA_BAD_REMOVAL);
intentFilter.addDataScheme("file");
registerReceiver(sdcardListener, intentFilter);
}

unregisterReceiver(sdcardListener);
