Question

我的应用程序在我的模拟器上完美运行，当我在手机上通过USB运行它时。但是，当我从PlayStore下载它时，它会在启动时崩溃这是日志：

java.lang.AbstractMethodError: abstract method "void android.app.Application$ActivityLifecycleCallbacks.onActivityCreated(android.app.Activity, android.os.Bundle)"

这是DispatchActivity：

package com.stackkedteam.feedshare;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;

import com.parse.ParseUser;

 /* Activity which starts an intent for either the logged in (MainActivity) or logged out
 * (SignUpOrLoginActivity) activity.
 */
public class DispatchActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        // Check if there is current user info
        if (ParseUser.getCurrentUser() != null) {
            // Start an intent for the logged in activity
            startActivity(new Intent(this, MealListActivity.class));
            finish();
        } else {
            // Start and intent for the logged out activity
            startActivity(new Intent(this, SignUpOrLoginActivity.class));
            finish();
        }
    }
}

我将包名从com.example.xxxxxx更改为com.stackkedteam.feedshare。是不是因为这个原因导致apk无法正常工作？

这是我的proguard-rules.pro：

# 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 SourceFile,LineNumberTable
-keep class com.parse.*{ *; }
-dontwarn com.parse.**
-dontwarn io.fabric.**
-dontwarn bolts.**
-dontwarn com.squareup.picasso.**
-keep class com.stackkedteam.feedshare.DispatchActivity {*;}
-keepclasseswithmembernames class * {
    native <methods>;
}

以下是我忽略生成APK的gradle消息警告：

enter image description here

这是gradle文件：

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }
}
apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

repositories {
    maven { url 'https://maven.fabric.io/public' }
}


android {
    compileSdkVersion 11
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "com.stackkedteam.feedshare"
        minSdkVersion 11
        targetSdkVersion 23
    }

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

dependencies {
    //compile 'com.android.support:support-v4:18.0.0'
    compile 'com.android.support:support-v4:23.0.+'
    compile files('libs/Parse-1.4.3.jar')
    compile 'com.parse.bolts:bolts-android:1.+'
    compile('com.crashlytics.sdk.android:crashlytics:2.5.3@aar') {
        transitive = true;
    }
}

Answer 1

显然，堆栈跟踪你的proguard文件需要进行一些修改。

-keep class com.parse。 {*; } -keep class io.fabric。 {*; }

因此，首先测试更改并查看在progurd运行时堆栈跟踪上剩下的内容

Answer 2

好的，事实证明我在

面前错过了一个星号

-keep class com.parse.**{ *;}

这就是解决方法。永远想弄清楚。

这是proguard文件：

# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in /Users/Ben/Library/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 SourceFile,LineNumberTable
-keep class com.parse.**{ *; }
-dontwarn com.parse.**
-dontwarn io.fabric.**
-dontwarn bolts.**
-dontwarn com.squareup.picasso.**
-keep class com.stackkedteam.feedshare.DispatchActivity {*;}
-keepclasseswithmembernames class * {
    native <methods>;
}
