选择释放模式时应用程序崩溃但在调试模式下运行完美

Question

我想减少我的应用程序的大小,因此我minifyEnabled true在发布模式下使用,但由于此应用程序崩溃.以下是我的

的build.gradle

 buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        // replace with the current version of the Android plugin
        classpath 'com.android.tools.build:gradle:1.1.0'
        // the latest version of the android-apt plugin
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.4'
    }
    }

    apply plugin: 'com.android.application'
    apply plugin: 'com.neenbedankt.android-apt'

    apt {
    arguments {
        androidManifestFile variant.outputs[0].processResources.manifestFile
        resourcePackageName android.defaultConfig.applicationId
     }
     }

     android {
     compileSdkVersion 21
     buildToolsVersion "21.1.2"

     defaultConfig {
        applicationId "com.iifl.news.codereduce"
        minSdkVersion 10
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    packagingOptions {

        exclude 'META-INF/LICENSE'
        exclude 'META-INF/NOTICE'

    }
    packagingOptions {
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/NOTICE'

    }
    }

    dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:support-v4:21.+'
    compile 'com.android.support:appcompat-v7:22.0.0'
    compile 'com.jakewharton:butterknife:5.0.+'
    compile 'com.jakewharton.timber:timber:2.2.+'
    compile 'com.squareup.dagger:dagger:1.2.+'
    provided 'com.squareup.dagger:dagger-compiler:1.2.+'
    apt 'com.squareup.dagger:dagger-compiler:1.2.2'


    compile 'com.squareup.okhttp:okhttp:2.0.0'
    compile 'com.squareup.okhttp:okhttp-urlconnection:2.0.0'
    compile 'com.squareup.retrofit:retrofit:1.6.1'
    compile 'com.fasterxml.jackson.core:jackson-databind:2.4.+'
    compile 'com.fasterxml.jackson.core:jackson-core:2.4.+'
    compile 'com.fasterxml.jackson.core:jackson-annotations:2.4.+'
    compile 'com.github.satyan:sugar:1.3'
    compile 'com.pnikosis:materialish-progress:1.2'
    compile 'com.android.support:cardview-v7:21.0.3'
    compile 'com.google.android.gms:play-services-analytics:7.0.0'

    compile files('libs/volley.jar')
   }

我添加了proguard-rules.pro.如果我删除它然后它给了我多个警告.

-keep class butterknife.** { *; }
-dontwarn butterknife.internal.**

-dontwarn retrofit.**

-dontwarn okio.**
-dontwarn    com.squareup.okhttp.internal.huc.JavaApiConverter$CacheHttpURLConnection

我的清单就像:

我的IIFLApplication类是这样的:

    public class IIFLApplication extends Application {

    private ObjectGraph applicationGraph;
    private Tracker tracker;

    private static final String PROPERTY_ID = "UA-61984632-2";

    public static int GENERAL_TRACKER = 0;

    public enum TrackerName {
        APP_TRACKER, GLOBAL_TRACKER, ECOMMERCE_TRACKER,
    }

    public HashMap mTrackers = new HashMap();

    @Override
    public void onCreate() {
        super.onCreate();
        /*if (BuildConfig.DEBUG) {
            Timber.plant(new DebugTree());
        } else {
            //Timber.plant(new CrashlyticsTree());
        }*/

        //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;
    }

    /**
     * A tree which logs important information for crash reporting.
     */
    private static class CrashlyticsTree extends Timber.HollowTree {
        @Override
        public void v(String message, Object... args) {
            logMessage(message, args);
        }

        @Override

        }

        @Override

        }

        @Override

            // NOTE: We are explicitly not sending the exception to Crashlytics here.
        }

        @Override

        }

            logMessage("WARN: " + message, args);
            // NOTE: We are explicitly not sending the exception to Crashlytics here.
        }

        @Override

            logMessage("ERROR: " + message, args);
        }

        @Override

            //Crashlytics.logException(t);

        private void logMessage(String message, Object... args) {
            //Crashlytics.log(String.format(message, args));
        }
    }



    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.但我没有弄到我做错了什么.任何消化不良将不胜感激.提前致谢

Folllowing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.** 但仍处于发布模式,它崩溃并且在调试模式下运行良好.

我也尝试过添加androidTestApt 'com.squareup.dagger:dagger-compiler:1.2.2'依赖项.但没有运气

我有同样的问题。问题是 proguard 正在应用程序启动时删除未使用的类方法，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时。您需要将 minifyEnabled 属性更改为 false 以永久保留未使用的方法。但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'
    }

Answer 2

如果您正在使用，Retrofit我假设您将拥有将用作 POJO 以从 JSON 转换为的类。（即当 Retrofit 返回响应时创建的 Java 对象）

这些类不应被混淆器混淆，您需要按如下方式删除它们（将它们放入单个包中会有所帮助！）：

-keep class com.app.example.{ *; }
-dontwarn com.app.example.**
