我在使用 Android studio 构建 android 应用程序时遇到此错误:

24192-24192/com.mkapp.apps.demo1 W/dalvikvm﹕ VFY: unable to find class referenced in signature (Landroid/os/PersistableBundle;)

我的依赖:

    compile 'com.android.support:support-v4:22.2.1'
    compile 'com.google.android.gms:play-services:7.3.0'
    compile 'com.android.support:appcompat-v7:22.1.0+'
    compile 'com.android.support:multidex:1.0.1'

非常感谢你的帮助

继承自 AppcompatActivity 的旧 Activity 运行良好。但是如果我创建一个新的，它就会出错。 这是我的 gradle.build :

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.0"

    defaultConfig {
        applicationId "com.mkapp.apps.demo1"
        minSdkVersion 10
        targetSdkVersion 22
        compileOptions {
            sourceCompatibility JavaVersion.VERSION_1_7
            targetCompatibility JavaVersion.VERSION_1_7
        }
        multiDexEnabled true
    }
    dexOptions {
        incremental true
        javaMaxHeapSize "4g"
    }
    packagingOptions {
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
    }
    lintOptions {
        checkReleaseBuilds false
        // Or, if you prefer, you can continue to check for errors in release builds,
        // but continue the build even when errors are found:
        abortOnError false
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

最佳答案

您遇到此问题是因为您正在尝试使用 onCreate (Bundle savedInstanceState, PersistableBundle persistentState) ，但此方法仅适用于 API 级别 21。

我能够在 Android 4.4 上使用此示例代码重现该问题:

public class TourActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState, new PersistableBundle());
    }

    @Override
    public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {
        super.onCreate(savedInstanceState, persistentState);
    }
}

问题已解决，删除了所有 PersistableBundle:

public class TourActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }
}

检查您在 TourActivity 中使用 PersistableBundle 的位置并将其删除或使用您的 Activity 代码更新您的答案。
