Android开发，获取U盘的路径

• 通过广播获取状态

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.text.TextUtils;

public class USBDiskReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        String path = intent.getData().getPath();
        if (!TextUtils.isEmpty(path)) {
            if ("android.intent.action.MEDIA_MOUNTED".equals(action)) {
                System.out.println("U盘路径----"+ path);
            }
            if ("android.intent.action.MEDIA_REMOVED".equals(action)) {
                System.out.println("U盘拨出----");
            }
        }
    }
}

• 在清单文件(AndroidManifest.xml)中注册

    <receiver android:name=".USBDiskReceiver">
            <intent-filter android:priority="999" >
                <action android:name="android.intent.action.MEDIA_MOUNTED" />
                <action android:name="android.intent.action.MEDIA_UNMOUNTED" />
                <action android:name="android.intent.action.MEDIA_REMOVED" />
                <data android:scheme="file" />
            </intent-filter>
        </receiver>
