Question

我正在使用android支持库v4和v7但这些库导致错误我不知道这里有什么问题。

我在NotificationCompat，NotificationManager，ViewCompat

中遇到错误

我在支持库中使用的所有内容都会在生成apk时导致错误。

这是我的gradle文件

compile project(':listViewLibrary')

compile 'com.google.code.gson:gson:2.2.4'
compile files('libs/AF-Android-SDK-v3.3.0.jar')
compile files('libs/android-query.0.26.7.jar')
compile files('libs/asmack-android-6-0.8.1.1.jar')
compile files('libs/PayPalAndroidSDK.jar')
compile files('libs/picasso-2.5.2.jar')
compile files('libs/volley.jar')
compile files('libs/gcm.jar')

compile project(':library')
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:recyclerview-v7:23.1.1'
compile 'de.hdodenhof:circleimageview:2.0.0'
compile 'com.facebook.android:facebook-android-sdk:4.10.0'
compile 'com.github.frank-zhu:pullzoomview:1.0.0'
compile 'com.google.android.gms:play-services-maps:8.4.0'
compile 'com.google.android.gms:play-services-analytics:8.4.0'
compile 'com.android.support:support-v4:23.1.1'
compile 'com.rockerhieu.emojicon:library:1.3.3'

以下是我收到错误的代码

                | (tp.getColor() & 0x00FFFFFF);
        tp.setColor(color);
    }
}
}

和第二个文件

NotificationCompat.InboxStyle inboxStyle = new NotificationCompat.InboxStyle();

mNotificationManager.notify(999, mBuilder.build());
