监听SD卡插拔广播

一：在AndroidManifest.xml文件中一定要在intent-filter中加上<data android:scheme=”file”>，否则无法监听到SD卡插拔广播；

二：如果在Activity里面用代码注册广播，那也一定要加iFilter.addDataScheme("file")。

在AndroidManifest.xml文件中打开权限：<uses-permission
android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />

具体监听方法可参考：

<!-- 往sdcard中写入数据的权限 -->

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

<!-- 在sdcard中创建/删除文件的权限 -->

<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />

eg：

//---------TF卡拔出 广播接收代码------------
protected TfBroadcastReceiver tfReceiver;
public class TfBroadcastReceiver extends BroadcastReceiver {
public TfBroadcastReceiver() {}

@Override
public void onReceive(Context arg0, Intent intent) {
Log.i("sxy", "tf卡拔出！！！");
if(hasTfFile)
{
BookSelectActivity.this.setResult(RESULT_CANCELED, null);
BookSelectActivity.this.finish();
}
}
}

private final static String tf_EJECT = "android.intent.action.MEDIA_EJECT";//tf卡弹出
//注册TF卡拔出广播
private void registerTfReceiver()
{
Log.i("sxy", "注册TF卡拔出广播");
hasTfFile = false;

IntentFilter actionFilter = new IntentFilter(tf_EJECT);
actionFilter.addDataScheme("file");
tfReceiver = new TfBroadcastReceiver();
registerReceiver(tfReceiver, actionFilter);
}

//取消TF卡拔出广播的注册
private void unregisterTfReceiver()
{
Log.i("sxy", "取消TF卡拔出广播的注册");
hasTfFile = false;

unregisterReceiver(tfReceiver);
}
