问题
I create an Edittext at my page, to allow user to update the apps by downloading the apk and install. I am using loojp library to handle the Asynctask.
My code at activity:
f0textupdate.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(final View view) {
try {
view.setEnabled(false);
final ProgressBar f0progress = (ProgressBar) findViewById(R.id.f0progress);
f0progress.setProgress(0);
mHttpClient.get("http://google.com/apps.apk", new FileAsyncHttpResponseHandler(lastcreated) {
@Override
public void onSuccess(int i, Header[] headers, File file) {
//sendBroadcast(new Intent(Intent.ACTION_INSTALL_PACKAGE, Uri.fromFile(file)));
try {
String path = file.getParent()+"/"+ CfgMain.siteid+ ".apk";
File dst = new File(path);
if (!dst.exists()) {
try {
dst.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
}
InputStream in = new FileInputStream(file);
OutputStream out = new FileOutputStream(dst);
// Transfer bytes from in to out
byte[] buf = new byte[1024];
int len;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
}
in.close();
out.close();
Intent installIntent = new Intent();
installIntent.setAction(Intent.ACTION_INSTALL_PACKAGE);
installIntent.setDataAndType(Uri.fromFile(dst), "application/vnd.android.package-archive");
installIntent.putExtra(Intent.EXTRA_NOT_UNKNOWN_SOURCE, true);
installIntent.putExtra(Intent.EXTRA_RETURN_RESULT, true);
installIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(installIntent);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
@Override
public void onFailure(int i, Header[] headers, Throwable throwable, File file) {
if (file.exists()) {
file.delete();
}
}
@Override
public void onProgress(long bytesWritten, long totalSize) {
int totProgress = (int) (((float) bytesWritten * 100) / totalSize);
if (totProgress > 0) {
f0progress.setVisibility(View.VISIBLE);
f0progress.setProgress(totProgress);
}
}
});
} catch (Exception ex) {
}
}
});
Manifest.xml
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERACT_ACROSS_USERS_FULL" />
<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES" />
It prompt an error message "Package parse error".
1) do I need to convert the filename as per the original apk name after download, as the "File file" seem storing as a temporarily name without extension
Update 1 Error from logCat:
05-17 11:17:19.142 4562-4562/? W/zipro﹕ Unable to open zip '/data/data/com.M28/cache/77lori.apk': Permission denied
05-17 11:17:19.152 4562-4562/? W/PackageParser﹕ Unable to read AndroidManifest.xml of /data/data/com.MMM/cache/MM.apk java.io.FileNotFoundException: AndroidManifest.xml
Update 1.1 - change the Onsuccess()
- add in additional permission at Manifest.xml
回答1:
Ok found a solution from other forum(xamarin) and solve my problem.. You need to save the APK to a public directory.
For example:
String path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS)+"/MM.apk";

That may be the issue with min sdk version. if you tried to install on lower sdk then you might get this type of error
