Android 应用程序升级本身似乎正确，但没有任何反应

Question

I googled for an app upgrading itself from.apk file. Here is code. But nothing happens. No error, just nothing. I tested on Android 12.

try {
    Intent install = new Intent(Intent.ACTION_VIEW);
    install.setDataAndType(Uri.parse("content://" + ApkFile_FullPath), "application/vnd.android.package-archive");
    install.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);
    startActivity(install);
} catch (Exception e){
    Log.i("aaaaa: ", "intent: " + e.getMessage());
}

Permissions in AndroidManifest.xml as follows:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" tools:ignore="ScopedStorage" />
<uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE" tools:ignore="ScopedStorage" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.CAMERA" />

Is it even possible to upgrade itself?

Simple solution to install an apk in 4 steps:

1. Add these permissions in AndroidManifest.xml: code

2. Add this inside the <application> tag in AndroidManifest.xml: code

3. Create a file named file_paths.xml in xml folder in res : code

4. Use this method to install an apk file. : code

Happy Coding!
