Enabling Feature

Initialization requires enabling Crash and ANR monitoring, which by default monitors Crash and ANR information.
// ModeStable mode by default includes Crash and ANR monitoring.
QAPM.beginScene(QAPM.SCENE_ALL, QAPM.ModeStable);
QAPM provides APIs for uploading custom log files in case of crashes or ANRs, if necessary. An example is as follows:
QAPM.setProperty(QAPM.PropertyExtraDataListener, new IExtraDataListener() {
    // This callback is executed when an ANR occurs.
    @Override
    public List<String> onAnrExtraFileHandler() {
        List<String> files = new ArrayList<>();
        File[] fileArray = new File("xxxx").listFiles();//Enter the folder name at xxx.
        for (File file : fileArray) {
            files.add(file.getAbsolutePath());
        }
        return files;
    }
    // This callback is executed when a crash occurs.
    @Override
    public List<String> onCrashExtraFileHandler() {
        List<String> files = new ArrayList<>();
        File[] fileArray = new File("xxxx").listFiles();//Enter the folder name at xxx.
        for (File file : fileArray) {
            files.add(file.getAbsolutePath());
        }
        return files;
    }
});
