总结：

二、混淆带有第三方jar包的apk    在proguard-project.txt加上以下三句         -libraryjars ./libs/xx.jar    //引入的第三方jar包        -dontwarn com.samsung.android.sdk.bt.gatt.**    //忽略混淆时第三方jar包的警告， “com.samsung.android.sdk.bt.gatt”为包名        -keep class com.samsung.android.sdk.bt.gatt.** {*;}    //不混淆第三方jar包，“com.samsung.android.sdk.bt.gatt”为包名
