只能贴代码，本想上传demo的，找不到地方
public class MainActivity extends Activity {
private Button mBut_download;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mBut_download = (Button)findViewById(R.id.mBut_download);
mBut_download.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
intoDownloadManager();
}
});
}
@SuppressLint("NewApi")
@TargetApi(Build.VERSION_CODES.GINGERBREAD)
private void intoDownloadManager(){
DownloadManager dManager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
Uri uri = Uri.parse("http://dingphone.ufile.ucloud.com.cn/apk/guanwang/time2plato.apk");
Request request = new Request(uri);
// 设置下载路径和文件名

long refernece = dManager.enqueue(request);
// 把当前下载的ID保存起来
SharedPreferences sPreferences = getSharedPreferences("downloadplato", 0);
sPreferences.edit().putLong("plato", refernece).commit();
}
}
public class DownLoadBroadcastReceiver extends BroadcastReceiver {
@SuppressLint("NewApi")
public void onReceive(Context context, Intent intent) {
long myDwonloadID = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, -1);

最后记者一定要注册广播
<receiver
android:name="com.example.apkdownloadmanager.DownLoadBroadcastReceiver">
<intent-filter>
<action android:name="android.intent.action.DOWNLOAD_COMPLETE" />
</intent-filter>
</receiver>
