Answer 1

尝试添加

defaultConfig {

    multiDexEnabled true 
    ...
}

在gradle中。它解决了我的问题。

Answer 2

从 app 级别添加build.gradle文件：

defaultConfig {
    multiDexEnabled true 
...
}

Answer 3

问题已解决。

错误是在一些png aapt试图压缩并发现不正确。

已添加

 aaptOptions{
        cruncherEnabled = false
    }

gradle解决了这个问题。

希望这可以帮助将来的某个人。

Answer 4

删除-rf你使用了gradle版本文件路径（.gradle / warpper / dists / gradle - ** .- all）。 它解决了我的问题

Answer 5

在build.gradle文件中添加依赖项：

implementation 'com.android.support:multidex:1.0.3'

在build.gradle的{​​{1}}部分中，添加：

defaultConfig

Answer 6

将实现import { UserService } from './user.service'; import { TestBed } from '@angular/core/testing'; import { environment } from 'src/environments/environment.prod'; import { AngularFireModule } from '@angular/fire'; describe('UserService unit tests', () => { let userService: UserService; beforeEach(() => { TestBed.configureTestingModule({ imports: [AngularFireModule.initializeApp(environment)], providers: [ { provide: UserService } ] }); userService = TestBed.get(UserService); }); it('should be created', () => { userService.hello(); }); }); 添加到Gradle构建中，然后在com.android.support:multidex:1.0.3中添加multiDexEnabled true。
