Currently, I need to update an installed application offline. To update the application, I have placed an apk file to the downloads folder of file manager and by pressing a button click event I want to update the apk but failed and facing an issue of "There was a problem while parsing the package error". I have rooted phone so is there any adb command or anything is available? I have also added exported="true" in manifest file and set allow to unknown permission for the app. Any help will be appreciable.
private void installApk() {
try {
String path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS)+"/Demo.apk";
File file = new File(path);
Intent intent = new Intent(Intent.ACTION_VIEW);
if (Build.VERSION.SDK_INT >= 24) {
Uri downloaded_apk = FileProvider.getUriForFile(MainActivity.this, getApplicationContext().getPackageName() + ".provider", file);
intent.setDataAndType(downloaded_apk, "application/vnd.android.package-archive");
List<ResolveInfo> resInfoList = getPackageManager().queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
for (ResolveInfo resolveInfo : resInfoList) {
grantUriPermission(getApplicationContext().getPackageName() + ".provider", downloaded_apk, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
}
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
// startActivity(intent);
} else {
intent.setAction(Intent.ACTION_VIEW);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.putExtra(Intent.EXTRA_NOT_UNKNOWN_SOURCE, true);
intent.setDataAndType(Uri.fromFile(file), "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
}
startActivity(intent);
} catch (Exception e) {
e.printStackTrace();
}
}
minsdk is 19 and maxsdk is 33
