Question

FolderViewModel

这是我在尝试构建release.apk时遇到的错误。

我尝试通过添加：

来修复它

<HierarchicalDataTemplate DataType="{x:Type viewModel:FolderViewModel}" ItemsSource="{Binding Path=Items}">
    <DockPanel>
        <Label Content="{Binding Name}" VerticalAlignment="Center" FontWeight="SemiBold" />
    </DockPanel>
</HierarchicalDataTemplate>

release.apk现在正确构建，至少显然是这样。

但是当我在手机（或任何手机）上安装应用程序时，它会在启动时崩溃，我想当它开始用Picasso加载图像时。

请帮我解决这个问题。

我已经尝试了一些在互联网上找到的解决方案并向您建议，它们似乎都可以正确构建，但应用程序仍然会崩溃。它可能取决于专业防守规则以外的其他东西吗？

这就是我的gradle的样子：

-dontwarn com.squareup.picasso.**

Answer 1

你似乎还在缩小OkHTTP

can't find referenced class com.squareup.okhttp

转到Picasso's Github page

-dontwarn com.squareup.okhttp.**

Answer 2

试试这些你的proguard.cfg：

#### -- Picasso --
 -dontwarn com.squareup.picasso.**

 #### -- OkHttp --

 -dontwarn com.squareup.okhttp.internal.**

 #### -- Apache Commons --

 -dontwarn org.apache.commons.logging.**

Answer 3

在您的应用gradle中尝试

minifyEnabled false 收缩资源为假

Answer 4

我的问题是我无法使用minifyEnabled true生成签名的apk，并且通过将以下内容添加到proguard-rules.pro文件中来修复了该问题：

#for Picasso library
-dontwarn okio.
# JSR 305 annotations are for embedding nullability information.
-dontwarn javax.annotation.**
# A resource is loaded with a relative path so the package of this class must be preserved.
-keepnames class okhttp3.internal.publicsuffix.PublicSuffixDatabase
# Animal Sniffer compileOnly dependency to ensure APIs are compatible with older versions of Java.
-dontwarn org.codehaus.mojo.animal_sniffer.*
# OkHttp platform used only on JVM and when Conscrypt dependency is available.
-dontwarn okhttp3.internal.platform.ConscryptPlatform

或者如果以上仍然引起问题，则可以使用以下内容：

#for Picasso library
-dontwarn com.squareup.okhttp3.**
-keep class com.squareup.okhttp3.* { *;}
-dontwarn okio.
-dontwarn okhttp3.internal.platform.ConscryptPlatform
-dontwarn javax.annotation.Nullable
-dontwarn javax.annotation.ParametersAreNonnullByDefault

Answer 5

解决了在proguard-rules.pro中添加这一行的问题：

-dontwarn com.squareup.okhttp.**

应用程序崩溃与毕加索和minifyEnabled真实
