android - Android Studio升级Gradle错误

Question

我正在使用Google Service Gradle

compile 'com.google.android.gms:play-services:8.1.0'
=> Bitmap bitmap = BitmapFactory.decodeFile(imagePath); // return bitmap

当我升级到

compile 'com.google.android.gms:play-services-ads:8.4.0'
=> Bitmap bitmap = BitmapFactory.decodeFile(imagePath); // return null ??!!

为什么会这样呢？解决方案是什么？

Answer 1

i am using same gradle
compile 'com.google.android.gms:play-services-ads:8.4.0'
i am sure issue is with your file path
check below code for testing put an image test.jpg in your DCIM folder and run this code
ImageView imageView = (ImageView) view.findViewById(R.id.imageView);
            String imageInSD = "/sdcard/DCIM/test.jpg";            
            Bitmap bitmap = BitmapFactory.decodeFile(imageInSD);
            if(bitmap == null){
                Toast.makeText(getActivity(),"not found",Toast.LENGTH_SHORT).show();
            }
            else {
                Toast.makeText(getActivity(),"found",Toast.LENGTH_SHORT).show();
                imageView.setImageBitmap(bitmap);
            }
