首页 > 解决方案 > Android 8.1 在调用 startActivityForResult() 时关闭 Activity

问题描述

有人来救我。我正在构建一个需要从设备相机拍照并将缩略图加载到 ImageView 的 android 应用程序,请注意我不想保存此图像,我只想将其加载到 ImageView 并从ImageView 稍后。

这就是我已经实现的:启动相机:

Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        if(cameraIntent.resolveActivity(activityWeakReference.get().getPackageManager()) != null){
startActivityForResult(cameraIntent, UPLOAD_PICTURE_CAMERA);
}

onActivityResult(int requestCode, int resultCode, Intent data)调用时调用以下内容startActivityForResult()

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == Activity.RESULT_OK && requestCode == UPLOAD_PICTURE_CAMERA) {
try{
                    Bundle extras = data.getExtras();
                    Bitmap imageBitmap = (Bitmap) extras.get("data");
                    imageViewphoto.setImageBitmap(imageBitmap);

                }catch (Exception e){
                    Log.e(TAG, Utility.stringify(e));
                }
}

问题:上面的代码在 android 7.0 上运行良好,但在 Oreo 8.1 上,活动在相机打开后立即关闭,因此onActivityResult()不会被调用。

这是我能得到的所有日志:

I/PhoneWindow: isNeedChangeStatusBarColor taskInfo: [android.app.ActivityManager$RunningTaskInfo@c7a24ee] size: 1
    isAPPNeedChangeSBColor pkgName: com.a3lineng.softwaredev.freedom_app needKeep: false

解决方案


在我的情况下,我已经能够弄清楚这一点,我发现它是在设备上启用的名为 Kill Background Activities 的用户设置。我所做的只是取消选中它,调用活动可用于接收来自相机意图的结果。

感谢您的帮助。
