Problem installing APK automatically into target board

I'll post my code if needed, but currently the only problem I'm facing is that I cannot insert the file path into InputStream.
I'm working on vendor directory,
The logic is quite simple
I use BroadcastReceiver to get USB_ATTACHED intent
start InstallPackage.class(my code) to install apk in usb
in my AndroidManifest,

I tried

and a lot of other methods which also didn't work
need help desperately, have been working on this for days.
In my log it says

Getting error after updating android studio to 3.2

We are facing an error of default activity is not found after update android studio to version "3.2". On another PC, which is running lower version 3.1.4 of android studio, this same application is working. If anyone has a solution then please suggest us.
I have attached manifest file of screen shot of android studio for that error.

Hi i want to disable (delete) these permissions from my app
WRITE EXTERNAL STORAGE
READ_EXTERNAL_STORAGE
WAKE_LOCK
and disable using camera and taking photos
the source code of users permissions in my app, I am using android studio.
that is the source how will be the new ??

There is a line in your file that reads
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
and one that reads
<uses-permission android:name="android.permission.WAKE_LOCK" />
If you delete them and rerun gradle, your project will now no longer have those permissions.

Remove this lines from your
AndroidManifest.xml
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
to remove the permissions

You can't just remove permissions and hope your app to work if permissions are essential for that to work or triggered on user interaction like touching camera button to invoke camera and require camera permissions. If that app requires that permissions you remove those permission you will get errors especially that apps targets for above Android 6.0 with android:targetSdkVersion="25".
If you are hoping to publish that app with JUST RESKIN you will get a strike because publishing a spam app. You should do some modification on that app to be considered as modified work. You should also check licanse for license whether you are allowed to do or not.

I am not great at programming, so any tips would be extremely appreciated and helpful. The main problem is that android studio matches and other cases like that.

you use inline close tag and outline also just remove the (/) from the reciever tag, to be:
<reciever android:name="de.dfki.nocrastination.logging.BootCompleteReceiver" android:enabled="true" android:exported="false"> ==> removed "/"
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</reciever>
And add "/" to the last line to be

Build Failed, Missing Key Attribute (Android SDK)

I recently imported my project over from Eclipse ADT over to Android SDK. I'm trying to re-run my simulator but I am encountering a problem with my AndroidManifest.xml file which states: /Users/####/Documents/android/medicine/src/main/AndroidManifest.xml:13:13-30 Error: Missing one of the key attributes 'action#name,category#name' on element intent-filter at AndroidManifest.xml:13:13-30

check your these lines :

here you define intent filter but not any action so if you don't want to specify any action there just delete it or add any action that you want to listen,
