我的Android应用程序存在奇怪的共享引用问题

问题是设置为sharedPreferences的默认值正在更改,这取决于我是从Google Play Store安装应用程序,还是直接安装APK(或从Play Store安装后清除应用程序存储)。

从Play Store安装时,我的布尔值为false。

清除存储并再次运行,我的布尔值为真。

private void setShowStoragePermission(boolean permission){
    SharedPreferences sharedPreferences  = getSharedPreferences("storagePermission", MODE_PRIVATE);
    SharedPreferences.Editor editor = sharedPreferences.edit();
    editor.putBoolean("permission", permission).apply();
}

private boolean getShowStoragePermission(){
    SharedPreferences sharedPreferences  = getSharedPreferences("storagePermission", MODE_PRIVATE);
    return sharedPreferences.getBoolean("permission", true);
}

在第一次干净运行时,没有保存的sharedreferences,因此返回的值 getShowStoragePermission()返回true。但是,从Play Store安装时,如Toast在前几秒钟看到的那样,我会出错(“savedpermission:false”)。

你可以自己在 测试版 应用程序的: Link to app on Play store / /

我正在Android P DP4上测试这个应用程序。这个问题有什么解决办法吗?

主活动中的代码:

if(ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
        setToast("savedPermission: " + getShowStoragePermission(), Toast.LENGTH_LONG);
        //on first run from Google Play store @getShowStoragePermission returns false - need to return true
        if(getShowStoragePermission()) {
            ActivityCompat.requestPermissions(MainActivity.this,
                    new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
                    MY_PERMISSIONS_REQUEST_WRITE_EXTERNAL_STORAGE);
        } else {
            makeBingWallRequest(false);
        }
    }else{
        //storage permission granted manually from app settings or from dialog request
        createImageDir();
        makeBingWallRequest(true);
    }

如果设置了sharedreferences:

    private void makeBingWallRequest(boolean storagePermission){
    if(getDeviceInternetStatus(context) == null && getBingWallDay() == 0){
        bingImage.setImageDrawable(ContextCompat.getDrawable(context, R.drawable.bearcats));
        return;
    }
    if(!storagePermission){
       new BingWallpaper(MainActivity.this).execute(false);
    }else {
        Calendar now = Calendar.getInstance(TimeZone.getDefault());
        int day = now.get(Calendar.DAY_OF_MONTH);

        //on first run
        setToast("savedBingWallDay: " + getBingWallDay(), Toast.LENGTH_LONG);
        if(getBingWallDay() == FIRST_RUN_BING_IMAGE){
            saveBingWallDay();
            new BingWallpaper(MainActivity.this).execute(true);
            //every other run
        }else if (day != getBingWallDay()) {
           //if current time is past 3AM then make new request
            int hourIn24 = now.get(Calendar.HOUR_OF_DAY);
            if(hourIn24 >= BING_IMAGE_RESET_HOUR_IN_24){
                saveBingWallDay();
                new BingWallpaper(MainActivity.this).execute(true);
            }else loadBitmap();
        } else loadBitmap();
    }
}
