java - 无法在 <28 Api 上运行为 Api 28（使用 minSdk 21）制作的应用程序

问题描述

我用我的手机在 Api 28 上开发了我的应用程序，从来没有遇到任何问题，现在我的应用程序已经完成了，所以我构建了 apk 来测试它，并且在每部不在 Android 9 上的手机上安装都失败了（Api < 28）

使用 Api 27 的手机上的结果是“'theApp' has working”

compileSdkVersion 和 targetSdkVersion 是 28，minSdkVersion 是 21 并且构建是好的，但是即使 Api 是 21 < xx < 28 它也不起作用

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.penduleechecs"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.android.support:design:28.0.0'
    testImplementation 'junit:junit:4.12'
//    androidTestImplementation 'com.android.support.test:runner:1.0.2'
//    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

解决方案

这可能是因为图像分辨率。您尝试使用的图像可能位于低分辨率文件夹中。尝试将图像或位图移动到下一个更高分辨率的图像源。

例如，如果您的图像在 hdpi 中，请将其移动到 xhdpi 文件夹。最好的方法是生成/导入资源作为图像/矢量资产，以便将其分配在各个文件夹中以用于不同的分辨率。

如果您生成一个单独的 apk，这将增加 apk 的大小。在这种情况下，尝试为不同的分辨率生成多个 apk。
