Question

我的应用程序运行良好，直到最近。然后，我将compileSdk和buildTools更新为25.从那时起，我的应用程序在打开时不知不觉地崩溃了。将minSdkVersion设置为18可以解决问题，但是当我把它放回到21时，就会发生这种情况。附加堆栈跟踪和gradle文件的一部分

附加项目gradle文件的部分

    apply plugin: 'com.android.application'
apply plugin: 'io.fabric'



repositories {

    mavenCentral()

}
android {
    compileSdkVersion 25
    buildToolsVersion '25.0.2'
    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }
    }
    defaultConfig {

        minSdkVersion 21
        targetSdkVersion 21
        renderscriptTargetApi 19
        renderscriptSupportModeEnabled true
        // Enabling multidex support.
        multiDexEnabled true
    }



    dexOptions {
        javaMaxHeapSize "4g"
        jumboMode = true
    }

    useLibrary 'org.apache.http.legacy'

}

我在这里多次看到这些堆栈跟踪错误，但没有明确答案是什么问题。

我尝试清理和重建，清除Android Studio缓存，更新gradle版本和插件。似乎没有什么对我有用。

似乎问题依赖于一个或多个android支持库

compile 'com.android.support:appcompat-v7:25.1.0'
compile 'com.android.support:support-v4:25.1.0'
compile 'com.android.support:cardview-v7:25.1.0'
compile 'com.android.support:recyclerview-v7:25.1.0'

将所有这些恢复到24.1.0似乎解决了这个问题。但是，我在其后续版本中使用了一些功能，因此没有帮助。

我有同样的问题。我做了两件事来解决这个问题。

将以下内容添加到应用的build.gradle文件中。

android { ... dexOptions { preDexLibraries false } } 对我来说，由于关于RxJava2 BehaviourSubject的ClassNotFoundException而崩溃，因此禁用了解析它的prex forx。

禁用项目的即时运行。取消选中Settings -> Build, Execute, Deployment -> Instant Run -> Enable Instant Run

应用程序无法使用minSdk启动21
