I wrote a method to install apk in all version of android and it works until android 8 . but it seems android 8 do not response to this method
install_apk(File file) {
try {
if (file.exists()) {
String[] fileNameArray = file.getName().split(Pattern.quote("."));
if (fileNameArray[fileNameArray.length - 1].equals("apk")) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
Uri downloaded_apk = getFileUri(context, file);
Intent intent = new Intent(Intent.ACTION_VIEW).setDataAndType(downloaded_apk,
"application/vnd.android.package-archive");
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
context.startActivity(intent);
} else {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file),
"application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
and this method for get uri on api >= 23
Uri getFileUri(Context context, File file) {
return FileProvider.getUriForFile(context,
context.getApplicationContext().getPackageName() + ".HelperClasses.GenericFileProvider"
, file);
}
You should be add a new permission.
<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES"/>
