如何使用android studio开发遗留Android应用程序(api> = 10)？

Question

我正在尝试使用Gingerbread,api 10为我的(非常)旧Android手机开发应用程序.

但是使用android studio作为IDE,问题似乎永远存在:

• 在项目向导中,仅支持api> = 14
• 所以我选择14并希望稍后改变
• 我将build.gradle(:app)中的minSdkVersion更改为10 - > minSdkVersion 10 cannot be smaller than version 14 declared in library
• 所以我implementation 'com.android.support:appcompat-v7:26.1.0'改为implementation 'com.android.support:appcompat-v7:25.1.0'
• 我收到错误¹有些生成的gradle chache文件"values-v14.xml"缺少资源

......这就是我不知道如何继续下去的观点

正如我所想,这不可能是真的,一个项目抛出了manny错误,我没有创建一个单独的类并且没有编写一行代码,我尝试从命令行构建.

它有效,但我习惯了IDE功能,不喜欢错过它们.所以我的问题是:

如何使用android studio为api级别开发一个简单的Android应用程序？
是否有指导将项目安装到api 10？

我是否处于"正确"的道路上？

是否有一个api 10级应用程序的骨架项目,我可以导入(好像我可以在项目向导中选择api 10)？

我知道原因,谷歌不再支持api <14了.

我仍然不明白为什么我不能使用我完全健康的硬件.
我仍然希望能够为我的旧手机编写一个简单的应用程序.

编辑 我修改了我的gradle:app以匹配来自ישואוהבאותך的骨架项目.除了上面提到的尝试之外,我确实必须更改compileSdkVersion,targetSdkVersion和androidTestImplementation.文件现在看起来像这样:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    defaultConfig {
        applicationId "dj.kai.test_api10"
        minSdkVersion 10
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:25.4.0'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    testImplementation 'junit:junit:4.12'

    // this is the last support test for api >= 9
    androidTestImplementation 'com.android.support.test:runner:1.0.0'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.0'
}

Answer 1

您可以为API> = 9创建Android项目,制作项目没有技术限制.唯一的问题是Google不支持API <14以下的旧手机.从26开始的Google支持库不支持api <14.因此,您需要使用支持库25.您还需要使用允许API的支持测试版本10.

我已经为你创建了一个骨架项目.您可以访问https://github.com/isnotmenow/AndroidProjectForAPI9
