我正在尝试为非市场用户创建自动安装应用程序。我正在从私人服务下载APK文件并触发它进行安装。现在,一旦安装过程完成,我想以编程方式知道这一点,以便我可以删除APK文件。
现在问题是,我无法收到广泛的铸ACTION_PACKAGE_INSTALL
。我的代码不在onReceive里面。接收广播时出错
try {
//set the download URL, a url that points to a file on the internet
//this is the file to be downloaded
URL url = new URL("http://url/Downloads/App.apk");
//create the new connection
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
//and connect!
urlConnection.connect();
//set the path where we want to save the file
//in this case, going to save it on the root directory of the
//sd card.
File SDCardRoot = Environment.getExternalStorageDirectory();
//create a new file, specifying the path, and the filename
//which we want to save the file as.
File file = new File(SDCardRoot,"App.apk");
//this will be used to write the downloaded data into the file we created
FileOutputStream fileOutput = new FileOutputStream(file);
//this will be used in reading the data from the internet
InputStream inputStream = urlConnection.getInputStream();
//this is the total size of the file
int totalSize = urlConnection.getContentLength();
//variable to store total downloaded bytes
int downloadedSize = 0;
//create a buffer...
byte[] buffer = new byte[1024];
int bufferLength = 0; //used to store a temporary size of the buffer
//now, read through the input buffer and write the contents to the file
while ((bufferLength = inputStream.read(buffer)) > 0) {
//add the data in the buffer to the file in the file output stream (the file on the sd card
fileOutput.write(buffer, 0, bufferLength);
//add up the size so we know how much is downloaded
downloadedSize += bufferLength;
//this is where you would do something to report the prgress, like this maybe
// updateProgress(downloadedSize, totalSize);
}
//close the output stream when done
fileOutput.close();
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file), "application/vnd.android.package-archive");
startActivity(intent);
//catch some possible errors...
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
BroadcastReceiver myReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
if(intent.getAction().equals(Intent.ACTION_PACKAGE_INSTALL)){
Toast.makeText(AndroidActivity.this,"Hi", Toast.LENGTH_LONG).show();
}
}
};
registerReceiver(myReceiver, new IntentFilter("ACTION"));
unregisterReceiver(myReceiver);

是的,我同意你的看法,但我真正的问题是我不能够进去的onReceive – 2012-01-11 13:30:14
甚至改变和增加意图? – nandeesh 2012-01-11 13:31:53
我已经删除了onReceive中的if条件。 – 2012-01-11 13:34:20
