Android logcat不显示异常的全部数据？

Question

最近，在我的Android logcat中，我得到了这样的异常。

java.lang.NullPointerException: Attempt to invoke virtual method 'int ir.nililand.messenger.d.i.a()' on a null object reference
        at ir.nililand.messenger.pages.y.a(:267)

ir.nililand.messenger.d.i.a() 我的问题是我应该怎么做才能得到这样的信息->

Attempt to invoke virtual method 'java.io.Serializable android.os.Bundle.getSerializable(java.lang.String)' on a null object reference

我有这样的依赖关系

dependencies {

    implementation fileTree(dir: 'libs', include: ['*.jar'])

    testImplementation 'junit:junit:4.13'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
    implementation 'androidx.appcompat:appcompat:1.1.0'

....
}

我试过 android:debuggable="true" 在 AndroidManifest 治标不治本

我如何才能从错误中获得完整的信息？

Answer 1

在你的 build.gradle (:app) 文件，确保 minifyEnabled 是 false.

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
    }
}

(设置 true 当你把它发布到公开场合(如Google Play Store)进行混淆时。)
