在我的android应用程序中，我们集成了Paypal Payment方法。它运作良好。但是我们无法生成Release Apk。请帮我找出解决方案。
这是我的日志

Warning:there were 24 unresolved references to classes or interfaces.
You may need to add missing library jars or update their versions.
If your code works fine without the missing classes, you can suppress
the warnings with '-dontwarn' options.

Proguard.txt文件
-dontwarn android.support.**
-dontwarn com.parse.*
-dontwarn com.paypal.android.*
-dontwarn com.google.android.gms.*
答案
你应该使用如下保持：
-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.** { *; }
另一答案
我有同样的问题。
将-dontwarn okio.**添加到proguard-project.txt为我解决了这个问题。
不确定，如果这可能会导致某些功能出现问题，但我的一次性付款工作正常。
伟大的工作Paypal。第一个v2.10.0停止工作，没有警告，v2.13.1需要额外的proguard东西......
另一答案
尝试将此代码添加到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/x86_64/libopencv_core.so'
exclude 'lib/x86_64/libopencv_imgproc.so'
}
}
另一答案
你需要在你的proguard文件中添加它：-dontwarn com.paypal.android.**而不是-dontwarn com.paypal.android.*
