Background: I am installing android app programmatically using PackageInstaller.
What am I doing: The code which I am using is mentioned below. This is the same code which has been provided in PackageInstaller sample by google.
private void init() {
PackageInstaller.Session session = null;
try {
PackageInstaller packageInstaller = getPackageManager().getPackageInstaller();
PackageInstaller.SessionParams params = new PackageInstaller.SessionParams(
PackageInstaller.SessionParams.MODE_FULL_INSTALL);
int sessionId = packageInstaller.createSession(params);
session = packageInstaller.openSession(sessionId);
addApkToInstallSession("HelloActivity.apk", session);
// Create an install status receiver.
Context context = InstallApkSessionApi.this;
Intent intent = new Intent(context, InstallApkSessionApi.class);
intent.setAction(PACKAGE_INSTALLED_ACTION);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
IntentSender statusReceiver = pendingIntent.getIntentSender();
// Commit the session (this will start the installation workflow).
session.commit(statusReceiver);
} catch (IOException e) {
throw new RuntimeException("Couldn't install package", e);
} catch (RuntimeException e) {
if (session != null) {
session.abandon();
}
throw e;
}
}
});
}
private void addApkToInstallSession(String assetName, PackageInstaller.Session session)
throws IOException {
// It's recommended to pass the file size to openWrite(). Otherwise installation may fail
// if the disk is almost full.
try (OutputStream packageInSession = session.openWrite("package", 0, -1);
InputStream is = getAssets().open(assetName)) {
byte[] buffer = new byte[16384];
int n;
while ((n = is.read(buffer)) >= 0) {
packageInSession.write(buffer, 0, n);
}
}
}
// Note: this Activity must run in singleTop launchMode for it to be able to receive the intent
// in onNewIntent().
@Override
protected void onNewIntent(Intent intent) {
Bundle extras = intent.getExtras();
if (PACKAGE_INSTALLED_ACTION.equals(intent.getAction())) {
int status = extras.getInt(PackageInstaller.EXTRA_STATUS);
String message = extras.getString(PackageInstaller.EXTRA_STATUS_MESSAGE);
switch (status) {
case PackageInstaller.STATUS_PENDING_USER_ACTION:
// This test app isn't privileged, so the user has to confirm the install.
Intent confirmIntent = (Intent) extras.get(Intent.EXTRA_INTENT);
startActivity(confirmIntent);
break;
case PackageInstaller.STATUS_SUCCESS:
Toast.makeText(this, "Install succeeded!", Toast.LENGTH_SHORT).show();
break;
case PackageInstaller.STATUS_FAILURE:
case PackageInstaller.STATUS_FAILURE_ABORTED:
case PackageInstaller.STATUS_FAILURE_BLOCKED:
case PackageInstaller.STATUS_FAILURE_CONFLICT:
case PackageInstaller.STATUS_FAILURE_INCOMPATIBLE:
case PackageInstaller.STATUS_FAILURE_INVALID:
case PackageInstaller.STATUS_FAILURE_STORAGE:
Toast.makeText(this, "Install failed! " + status + ", " + message,
Toast.LENGTH_SHORT).show();
break;
default:
Toast.makeText(this, "Unrecognized status received from installer: " + status,
Toast.LENGTH_SHORT).show();
}
}
}
Query: The code works perfectly fine but PackageInstaller doesn't give any status on clicking the INSTALL button where as onclicking the CANCEL button, it provides status. I have to perform some action when user confirms installation by clicking install button. Is there any other way to get the status when install button is clicked?
Note: I don't want the status after installation is successful but I want it when INSTALL button is clicked.
