这是我用按钮设置通知的代码.

Intent receiverIntent = new Intent(ctx, ResponsivePrefsActivity.class);
        PendingIntent pReceiverIntent = PendingIntent.getActivity(ctx, 1, receiverIntent, 0);
        Intent clearIntent = new Intent(ctx, ResponsivePrefsActivity.class);
        clearIntent.setAction("clear");
        PendingIntent pClearIntent = PendingIntent.getActivity(ctx, 1, clearIntent, 0);

        Intent colorsIntent = new Intent(ctx, ResponsivePrefsActivity.class);
        colorsIntent.setAction("colors");
        PendingIntent pColorsIntent = PendingIntent.getActivity(ctx, 1, colorsIntent, 0);

        Intent animationIntent = new Intent(ctx, ResponsivePrefsActivity.class);
        animationIntent.setAction("animation");
        PendingIntent pAnimation = PendingIntent.getActivity(ctx, 1, animationIntent, 0);

        Notification.Builder builder;
        builder = new Notification.Builder(ctx).setSmallIcon(R.drawable.ic_launcher).setAutoCancel(false)
                .setContentTitle("Draw Me: A Live Wallpaper").setContentText("Never get bored again!")
                .setContentIntent(pReceiverIntent).addAction(R.raw.ic_menu_close_clear_cancel, "Clear", pClearIntent)
                .addAction(R.raw.ic_menu_edit, "Colors", pColorsIntent).addAction(R.raw.ic_menu_play_clip, "Animation", pAnimation);
        Notification notification …

我正在使用FileProvider从设备中获取照片.实现在调试版本中运行得很好(minifyEnabled false)但是当我构建版本构建(minifyEnabled为true)时,我收到一个错误:

java.lang.RuntimeException: Unable to get provider android.support.v4.content.FileProvider: 
java.lang.ClassNotFoundException: Didn't find class "android.support.v4.content.FileProvider" 
on path: DexPathList[[zip file "/data/app/com.package.name-2/base.apk"],
nativeLibraryDirectories=[/data/app/om.package.name-2/lib/arm, /vendor/lib, /system/lib]]

所以我猜这与proguard设置有关

我有

compile 'com.android.support:support-v13:23.1.1'

这是我的gradle文件中的v4的超集

minSdkVersion 21
targetSdkVersion 23

和

-keep class android.support.v4.app.** { *; }
-keep class android.support.v4.content.** { *; }
-keep interface android.support.v4.app.** { *; }
-keep interface android.support.v4.content.** { *; }
-keep class * extends android.content.ContentProvider

在我的proguard-rules.pro文件中

我已经测试了Android 5和6,同样的事情发生了.任何建议都会有用,提前谢谢.
