【中文标题】选择发布模式时应用程序崩溃但在调试模式下完美运行【英文标题】:App crashes when select Release mode but in debug mode works perfectly 【发布时间】:2015-08-04 06:46:24 【问题描述】:我想减小应用程序的大小,因此我在发布模式下使用minifyEnabled true
,但由于此应用程序崩溃。以下是我的

我添加了 proguard-rules.pro。如果我删除它,它会给我多个警告。

我的 IIFLApplication 类是这样的:

public static int GENERAL_TRACKER = 0;

//create object graph
applicationGraph = ObjectGraph.create(getModules().toArray());
applicationGraph.inject(this);
private List<Object> getModules()
return Arrays.<Object>asList(new AppModule(this));
public ObjectGraph getApplicationGraph()
return this.applicationGraph;
/**

public synchronized Tracker getTracker(TrackerName appTracker)
if (!mTrackers.containsKey(appTracker))
GoogleAnalytics analytics = GoogleAnalytics.getInstance(this);
Tracker t = (appTracker == TrackerName.APP_TRACKER) ? analytics.newTracker(PROPERTY_ID) : (appTracker == TrackerName.GLOBAL_TRACKER) ? analytics.newTracker(R.xml.global_tracker) : analytics.newTracker(R.xml.ecommerce_tracker);
mTrackers.put(appTracker, t);
return (Tracker) mTrackers.get(appTracker);
我认为是由于proguard。但我没有明白我做错了什么。任何 suugestion 将不胜感激。提前致谢
以下是我的 logcat:应用程序在运行后立即崩溃。

我也尝试过使用-keep class com.iifl.news.codereduce. *;
-dontwarn com.iifl.news.codereduce.**
,但仍然在发布模式下崩溃,在调试模式下运行良好。
我还尝试在依赖项中添加androidTestApt 'com.squareup.dagger:dagger-compiler:1.2.2'
。但是没有运气
【问题讨论】:
@HarshDattani logcat 已添加 您能否查看您的 mapping.txt 文件并找到com.iifl.news.codereduce.a.b
应该是什么并将该混淆类的代码添加到您的问题中? (如果不是 AppModule)
【参考方案1】:
我遇到了同样的问题。问题是 proguard 在应用程序启动时删除了未使用的类方法,但应用程序稍后可能需要这些类方法,例如当您切换到其他活动或退出应用程序时,那就是应用程序崩溃的时候。您需要将 minifyEnabled 属性更改为 false 以永久保留未使用的方法。但是您仍然可以在发布期间使用收缩属性收缩所有文件。缩小可能会提高应用程序的性能。
release
minifyEnabled false //keeps unused methods instead of removing them
shrinkResources true //to shrink files
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
【讨论】:
我添加了shrinkResources true
并得到了这个 gradle 构建错误:删除未使用的资源需要打开未使用的代码收缩。请参阅d.android.com/r/tools/shrink-resources.html 了解更多信息。
这是错误的答案,如果假设我必须启用 proguard 并想保护我的代码,那么我该怎么办?因为在发布版本中启用 proguard 时应用程序会崩溃,而在 debud 中它可以正常工作。【参考方案2】:
从build.gradle
文件中删除apt 'com.squareup.dagger:dagger-compiler:1.2.1
。
【讨论】:
我也尝试了你的建议,但仍然是同样的错误。谢谢 请详细说明为什么这会有所帮助。【参考方案3】:如果您使用Retrofit
,我假设您将拥有将用作 POJO 以从 JSON 转换为的类。 (即 Retrofit 返回响应时创建的 Java 对象)
这些类不应被 proguard 混淆,您需要按如下方式删除它们(将它们放在单个包中会有所帮助!):
-keep class com.app.example. *;
-dontwarn com.app.example.**
【讨论】:
感谢您的建议。我已经按照你的建议做了,但我仍然遇到同样的错误。 您还有什么建议吗?我仍然深陷其中。谷歌很多,但没有得到提示。以上是关于选择发布模式时应用程序崩溃但在调试模式下完美运行的主要内容,如果未能解决你的问题,请参考以下文章
发布 apk 安装但启动时崩溃。该应用程序在调试模式下完美运行。我查看了 Android Studio,这是我的 adb logcat。
