I create a screenshot application and that work good in all of the android devices.
But I have a problem with take screenshot in android 12 (Xiaomi 11t) I'm using static intent and result code and then clone intent and pass it to this function mediaProjectionManager.getMediaProjection(resultCode,clonedIntent) I have no problem with take screen shot for first time but I can't take screen shot for second time and I get this error.
if you need more info please tell me.

MIUI13+Android12
The RemoteException error is reported on line 553 of MediaProjectionManagerService. After checking the source code, the error message is that the package for applying for mediaprojection cannot be found.
It is guessed that MIUI maintains a separate list for this, only the package that has applied for permission will be in it, and it will be removed after obtaining and closing mediaprojection. No such mechanism has been seen in other systems.
In other words, intent data cannot be reused. The solution is also very simple, just don’t close the mediaprojection after using it.

Faced same error. You need to add dev access code.

Detect added libraries to pirated Android app?

It appears from my crash reports that some people pirate my app and add advertisements to monetise it.
The stack trace from the crash report seems to show a bunch of calls to a library to show interstitials?
Is it possible for me to add code to detect the presence of the com.test.ylh or com.qq.e library?

You can check if a class exists with a method as described over here: How to check if class exists somewhere in package?
However, they could also remove that check when recompiling the app. So it won't be airtight. You can make it more difficult for the "pirates" by adding proper code obfuscation: https://developer.android.com/studio/build/shrink-code#obfuscate

Using ACRA with tracepot as backend

I have just finished my first android app as part of a school project ..one of my friends encountered a problem while trying to explore one of the activities in the app ..so i searched for solutions to get the crashes reports whenever they happen to fix the bugs ..i came across ACRA ..and I followed one of SO threads to setup ACRA to my app ..
RESULT: when the crashs happens the gmail app get launch in the device and the user (if he want to) he'll send the crash report by email ..Consedering not all users will want to ..i found in a comment in one of the SO threads that some developers use tracepot.
so i have used their link for integration in formUri but exploring my account on tracepot i get nothing ..is there something i am doing wrong (or if there is a better solution than using tracepot a backend , please suggest/explain or link a good tutorial, thanks!)
MyApplication.Java ( AFTER EDITING
#ReportsCrashes(
formUri = "https://collector.tracepot.com/79b1***",
reportType = org.acra.sender.HttpSender.Type.JSON,
httpMethod = org.acra.sender.HttpSender.Method.PUT,
mode = ReportingInteractionMode.TOAST,
resToastText = R.string.crash_toast_text
)
public class MyApplication extends Application {
#Override
public void onCreate() {
super.onCreate();
CaocConfig.Builder.create()
//.errorActivity(CustomErrorActivity.class) //default: null (default error activity)
.apply();
// The following line triggers the initialization of ACRA
ACRA.init(this);
}
}
EDIT :
msg in logcat if i use the http and email:

By default, if the mail config is present, Acra 4 will send via mail and nothing else.
To use both you'd have to configure the reportSenderFactories.
400: Client error
Indicates that tracepot rejected your report. This could have multiple reasons. To find out what the problem is, call ACRA.DEV_LOGGING = true; right before ACRA.init and post all logcat with the ACRA tag.
Also note that ACRA 4.9.2 does not support android Oreo and above, it is recommended to upgrade to at least ACRA 4.11, or just the newest version 5.2.0.

But I didn't find "dumpMessageHistory" in my code, please help, thanks!!

The class android.app.ANRAppManager can not be found in Android Application Framework (/frameworks/base/core/java/android/app). Probably it is a vendor supplied class for MTK chips. Whenever there is an ANR raised, ANRAppManager.dumpMessageHistory would be invoked.
The best advice would be to keep track of all cases of ANR that takes place in your app and try to fix it.
