问题是,在我使用此方法从服务器下载.apk文件后:
public void Update(String apkName) {
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
File file = new File("/sdcard/Download/"+ apkName + ".apk");
if (file.exists()) {
file.delete();
}
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS + "/", apkName + ".apk");
DownloadManager manager = (DownloadManager) getActivity().getSystemService(Context.DOWNLOAD_SERVICE);
manager.enqueue(request);
}
然后我使用BroadCastReciever在下载操作完成时采取安装操作,如下所示:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// some codes here...
BroadcastReceiver receiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(action)){
Intent i = new Intent(Intent.ACTION_VIEW);
i.setDataAndType(Uri.fromFile(new File(Environment.getExternalStorageDirectory() + "/Download/" + apkName + ".apk")),
"application/vnd.android.package-archive");
startActivity(i);
} else {
}
}
};
getActivity().registerReceiver(receiver, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));
download_apk(apkName);
return rootView;
}
现在问题是下载操作完成后,DownloadManager尝试安装apk文件,我得到this,这是“解析错误/解析包时出现问题”。
单击“确定”后,显示“真正的安装页面”(由broadcastReciever触发)。我在Activity中运行此进程,这非常好。如上所述,这次是碎片!这可能是原因??
如何从自动运行apk停止DownloadManager? 有人可以帮帮我吗?
