Android实践 -- 监听外置sdcard(TF卡)的插拔事

监听外置sdcard(TF卡)的插拔事件

在编码的过程中需要监听外置sdcard的插拔事件，在AndroidManifest.xml中注册一个静态广播
一定要添加上 <data android:scheme="file" />

<receiver android:name=".SdcardReceiver" android:enabled="true">
<intent-filter>
    <action android:name="android.intent.action.MEDIA_MOUNTED" />
      <action android:name="android.intent.action.MEDIA_UNMOUNTED" />
      <data android:scheme="file" />
</intent-filter>

</receiver>

在java代码中继承 BroadcastReceiver,监听到sdcard的插拔事件，然后做相应的逻辑操作

public class SdcardReceiver extends BroadcastReceiver{

  @Override
  public void onReceive(Context context, Intent intent) {
      String action = intent.getAction();
      if(action.equals(Intent.ACTION_MEDIA_MOUNTED)){
          Log.d("tag","sdcard mounted");
      }else if(action.equals(Intent.ACTION_MEDIA_UNMOUNTED)){
          Log.d("tag","sdcard unmounted");
      }
  }

}
