应用程序使用 proguard 崩溃

Question

由于我的 Proguard 错误，我的应用程序崩溃了。我也在某个地方发布了这个问题。 如何格式化 proguard 错误？请帮我解决这个问题：

我的 build.gradle：

apply plugin: 'com.android.application'
android {
compileSdkVersion 24
buildToolsVersion "24.0.1"
defaultConfig {
    applicationId 'com.quorate.android'
    minSdkVersion 16
    targetSdkVersion 24
    versionCode 3
    versionName "1.2"
    testInstrumentationRunner 'android.support.test.runner.AndroidJUnitRunner'
    vectorDrawables.useSupportLibrary = true
}
buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        signingConfig signingConfigs.debug
        debuggable true
    }
}
productFlavors {
}
}

configurations.all {
resolutionStrategy.force 'com.android.support:support-annotations:24.0.0'
}

dependencies {
testCompile 'junit:junit:4.12'
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'
androidTestCompile 'com.android.support.test:runner:0.5'
compile 'com.android.support:appcompat-v7:24.1.1'
compile 'com.android.support:recyclerview-v7:24.1.1'
compile 'com.android.support:cardview-v7:24.1.1'
compile 'com.android.support:design:24.1.1'
compile 'com.firebaseui:firebase-ui-database:0.4.3'
compile 'com.google.firebase:firebase-auth:9.2.1'
compile 'com.google.firebase:firebase-database:9.2.1'
compile 'com.android.support:support-v4:24.1.1'
compile 'com.google.firebase:firebase-core:9.2.1'
}

apply plugin: '

我的 proguard 规则 pro 文件：

# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in C:\Users\Vyshnav\AppData\Local\Android\Sdk/tools/proguard/proguard-    android.txt
# You can edit the include path and order by changing the proguardFiles
# directive in build.gradle.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html

# Add any project specific keep options here:

# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
#   public *;
#}

-keepattributes Signature
-keepattributes *Annotation*

-keep class com.quorate.android.PostViewHolder.** {
*;
 }

-keepclassmembers class com.quorate.android.User.** {
*;
 }

-keepclassmembers class com.quorate.android.Post.** {
*;
}

 -keepclassmembers class com.quorate.android.Comment.** {
*;
 }

logcat 错误：

好的，我自己解决了。谢谢你的帮助。我很感激。 我通过将“minify enabled true”更改为“minify enabled false”来解决它，因为问题是 Proguard。通过 Studio 调试时未显示它的原因是使用“即时运行”时 Proguard 会自动禁用。 解决这个问题需要 24 小时和严重的眼痛。希望这个答案有一天对某人有所帮助。 还有 StackOverflow 开发人员……你们真的需要想出新功能，这样像我这样的菜鸟才能更快地得到答案……也许我应该自己开发！

尝试在我们的 proguard 中添加以下行。

-keep public class android.support.v7.widget.** { *; } -keep public class android.support.v7.internal.widget.** { *; } -keep public class android.support.v7.internal.view.menu.** { *; }

否则，您可以尝试在 proguard 文件中使用 -printmapping myapplication.map 解码一些日志。解码后我们可以得到一些实际的日志
