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

Question

这个问题已经有答案了:

Android Canvas: drawing too large bitmap (17 个回答)

已关闭 4 年前。

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，所以我构建 apk 来测试它，但在每部非 Android 9 (Api < 28) 的手机上安装都会失败

使用 Api 27 的手机上的结果是“‘theApp’已正常工作”

compileSdkVersion 和 targetSdkVersion 为 28，minSdkVersion 为 21，构建正常，但即使 Api 为 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'
}

Answer 1

这可能是由于图像分辨率造成的。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，如果您的图像位于 hdpi 中，请将其移动到 xhdpi 文件夹中。最好的方法是生成/导入资源作为图像/vector 资源，以便将其分配到不同分辨率的各个文件夹中。

如果您生成一个 apk，这会增加 apk 的大小。在这种情况下，请尝试为不同的分辨率生成多个apk。
