無法在Android Studio中構建Release APK

Question

在我的Android應用程序中，我們集成了Paypal Payment方法。 它運作良好。 但是我們無法生成Release Apk。 請幫我找出解決方案。

這是我的日志

構建文件

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:recyclerview-v7:+'
    compile 'com.android.support:palette-v7:+'
    compile 'com.parse.bolts:bolts-android:1.+'

    compile 'com.mcxiaoke.volley:library-aar:1.0.0'
    compile 'com.paypal.sdk:paypal-android-sdk:2.13.1'
}

Proguard.txt文件

-dontwarn android.support.**
-dontwarn com.parse.*
-dontwarn com.paypal.android.*
-dontwarn com.google.android.gms.*

Answer 1

你應該保持如下：

-keep class android.support.** { *; }
-keep interface android.support.** { *; }

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

-keep class com.paypal.android.** { *; }
-keep interface com.paypal.android.** { *; }

-keep class com.google.android.gms.** { *; }
-keep interface com.google.android.gms.** { *; }

Answer 2

我有同樣的問題。

在proguard-project.txt中添加-dontwarn okio.**為我解決了這個問題。

不確定，如果這可能會導致某些功能出現問題，但我的一次性付款工作正常。

偉大的工作Paypal。 第一個v2.10.0停止工作，沒有警告，v2.13.1需要額外的proguard東西......

Answer 3

嘗試將此代碼添加到build.gradle文件中。

android{
packagingOptions{
        exclude 'AndroidManifest.xml'
        exclude 'lib/arm64-v8a/libcardioDecider.so'
        exclude 'lib/arm64-v8a/libcardioRecognizer.so'
        exclude 'lib/arm64-v8a/libcardioRecognizer_tegra2.so'
        exclude 'lib/arm64-v8a/libopencv_core.so'
        exclude 'lib/arm64-v8a/libopencv_imgproc.so'
        exclude 'lib/armeabi/libcardioDecider.so'
        exclude 'lib/armeabi-v7a/libcardioDecider.so'
        exclude 'lib/armeabi-v7a/libcardioRecognizer.so'
        exclude 'lib/armeabi-v7a/libcardioRecognizer_tegra2.so'
        exclude 'lib/armeabi-v7a/libopencv_core.so'
        exclude 'lib/armeabi-v7a/libopencv_imgproc.so'
        exclude 'lib/mips/libcardioDecider.so'
        exclude 'lib/x86/libcardioDecider.so'
        exclude 'lib/x86/libcardioRecognizer.so'
        exclude 'lib/x86/libcardioRecognizer_tegra2.so'
        exclude 'lib/x86/libopencv_core.so'
        exclude 'lib/x86/libopencv_imgproc.so'
        exclude 'lib/x86_64/libcardioDecider.so'
        exclude 'lib/x86_64/libcardioRecognizer.so'
        exclude 'lib/x86_64/libcardioRecognizer_tegra2.so'
        exclude 'lib/x86_64/libopencv_core.so'
        exclude 'lib/x86_64/libopencv_imgproc.so'
    }
}

Answer 4

你需要在你的proguard文件中添加它： -dontwarn com.paypal.android.**而不是-dontwarn com.paypal.android.*
