Android打包遇到的那些坑

说说今天打包遇到的坑，由于线上有个支付的bug需要紧急修复，而我们的项目又没有使用热修复，所以只能通过编译打包等传统流程，还好android上线比较快。

说说我进早上打包遇到的几个问题吧，首先我使用build-->generate signed apk然后输入签名打包，啪，给我报了一个错。

1，debug-stripped.ap_' specified for property 'resourceFile' does not exist.

这什么错，怎么一起没遇到过，马上度娘，找了半天找到一个和我很相似的，意思是android studio升级到2.2之后出现的错误，于是我也尝试了一把下面的方法：

File—>Settings，打开Settings界面，搜索到Instant Run。

,2怎么我的默认就是没选中的啊，于是看第二条，有人说是Debug模式下的混淆开关问题。

好我都把你改了，debug我都false行了吧，形如：

buildTypes {
    release {
        minifyEnabled true
        shrinkResources true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
    debug {
        minifyEnabled false
        shrinkResources false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

3，我又重新编译，结果报Android Studio 混淆打包 IOException: Please correct the above warnings first，形如下面的错误

好吧，我打开混淆文件（proguard-rules），首先我看到有人把下面的ignorewarning注释了，我擦，然后关闭，打包成功，不过这里加上下面的一段话

打包报错java.io.IOException: Please correct the above warnings first.
