Question

因此，我的应用程序在虚拟设备上运行时可以完美运行。当我尝试构建签名的apk时，出现以下错误：

//define the incrementing function
incrementer = function(property) {
value = mixpanel.get_property(property);

update = {}
//Ensure that 'value' has a type = number
if(value && typeof(value) == 'number') {
  update[property] = value +1;
}
else {
  update[property] = 1
}
  mixpanel.register(update);
};

因此我将其添加到了我的proguard文件中：

Warning: androidx.media.AudioAttributesCompatParcelizer: can't find referenced field 'android.support.v4.media.AudioAttributesImpl mImpl' in program class android.support.v4.media.AudioAttributesCompat
Warning: androidx.media.AudioAttributesImplApi21Parcelizer: can't find referenced field 'android.media.AudioAttributes mAudioAttributes' in program class android.support.v4.media.AudioAttributesImplApi21
Warning: androidx.media.AudioAttributesImplApi21Parcelizer: can't find referenced field 'int mLegacyStreamType' in program class android.support.v4.media.AudioAttributesImplApi21
Warning: androidx.media.AudioAttributesImplBaseParcelizer: can't find referenced field 'int mUsage' in program class android.support.v4.media.AudioAttributesImplBase
Warning: androidx.media.AudioAttributesImplBaseParcelizer: can't find referenced field 'int mFlags' in program class android.support.v4.media.AudioAttributesImplBase
Warning: androidx.media.AudioAttributesImplBaseParcelizer: can't find referenced field 'int mLegacyStream' in program class android.support.v4.media.AudioAttributesImplBase

现在apk可以成功构建，但是在我启动应用程序后，它因该错误而崩溃。当我的应用在虚拟设备上运行正常时，为什么会发生这种情况？

即使阅读其他答案，我似乎也找不到问题。这是我的xml代码：

-dontwarn android.support.v4.**

Answer 1

我想当您将minifyEnabled设置为false时，它将起作用。如果是这样，似乎您的proguard存在问题。尝试添加此行：

-keep class android.support.v7.widget.** { *; }

Answer 2

一切正常：

<TextView
  android:id="@+id/title_1"
  android:layout_width="277dp"
  android:layout_height="50dp"
  android:padding="5sp"
  android:paddingStart="10sp"
  android:text="@string/title"
  android:textColor="#ffffff"
  android:textSize="25sp"
  tools:ignore="RtlSymmetry"
 />

问题在这里：

  android:padding="5sp"
  Only you just need to change this thing android:padding="5dp"

Answer 3

我收到这些警告，并将这些行添加到我的proguard-rules.pro文件中：

-dontwarn androidx.**
-keep class androidx.** { *; }
-keep interface androidx.** { *; }
