android - 仅在发布时启动应用程序崩溃

Question

我的应用程序仅在 Release模式下启动时崩溃。我把 minifyEnabled 设置为 false 并且应用程序运行完美，但是如果我启用了 proguard 文件，应用程序就会崩溃。这是 build.gradle 文件的内容:

apply plugin: 'com.android.application'

repositories {
maven {
    url "https://oss.sonatype.org/content/repositories/snapshots"
   }
}

android {
compileSdkVersion 23
buildToolsVersion "23.0.1"
useLibrary 'org.apache.http.legacy'

defaultConfig {
    applicationId "com.example.myapp"
    minSdkVersion 9
    targetSdkVersion 23
    versionCode 1
    versionName "1.0.2"
}
buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

compileOptions {
    encoding "ISO-8859-1"
}
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:23.1.0'
compile 'com.android.support:support-v4:23.1.0'
compile 'com.android.support:recyclerview-v7:23.1.0'
compile 'com.google.android.gms:play-services:8.1.0'
compile 'com.github.rey5137:material:1.2.1.6-SNAPSHOT'
compile 'com.squareup.picasso:picasso:2.5.2'
compile 'com.google.android.gms:play-services-ads:8.1.0'
}

这些是我添加到 proguard-rules.pro 文件中的行:

-dontwarn android.support.v4.**
-keep class android.support.v4.** { *; }
-dontwarn android.support.v7.**
-keep class android.support.v7.** { *; }
-dontwarn com.squareup.okhttp.**
-dontwarn com.rey.material.**
-keep class com.rey.material.** { *; }
-dontwarn com.google.android.gms.ads.**

这是出现在 logcat 中的错误:

我的类 DataInfo 如下:

public class DataInfo implements Serializable, Parcelable {
protected int nIdDrawable;
protected String strName;
protected String strDrawable;
protected String strType;

public DataInfo(int nIdDrawable, String strName){
    this.nIdDrawable = nIdDrawable;
    this.strName = strName;
    this.strDrawable = "";
    this.strType = "";
}

public DataInfo(String strName, String strDrawable, String strType){
    this.nIdDrawable = 0;
    this.strName = strName;
    this.strDrawable = strDrawable;
    this.strType = strType;
}


/**
 * Constructs a Question from a Parcel
 * @param parcel Source Parcel
 */
public DataInfo (Parcel parcel) {
    this.nIdDrawable = parcel.readInt();
    this.strName = parcel.readString();
    this.strDrawable = parcel.readString();
    this.strType = parcel.readString();
}


// Method to recreate a Question from a Parcel
public static Parcelable.Creator<DataInfo> CREATOR = new Creator<DataInfo>() {

    @Override
    public DataInfo createFromParcel(Parcel source) {
        return new DataInfo(source);
    }

    @Override
    public DataInfo[] newArray(int size) {
        return new DataInfo[size];
    }

};


@Override
public int describeContents() {
    return 0;
}

@Override
public void writeToParcel(Parcel dest, int flags) {
// TODO Auto-generated method stub
    dest.writeInt(nIdDrawable);
    dest.writeString(strName);
    dest.writeString(strDrawable);
    dest.writeString(strType);
}
}

这可能是什么问题？我必须在 proguard 文件中再添加一些行吗？

提前致谢。

Answer 1

尝试添加

-keep class com.example.myapp.** { *; }

到您的 proguard 配置。这应该将您应用程序的所有类留在 apk 中。
