Question

我有一个Android应用程序在我的测试设备（API 17）上运行得很好。但是，当我在具有较高API的设备上运行相同的应用时（在这种情况下为22），该应用无法启动。

所有这些设备都是真正的设备而不是模拟器

    02/19 11:10:07: Launching app
$ adb shell am start -n "com.example.user.eafya/com.example.user.eafya.activities.FirstActivity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER
Error while executing: am start -n 
"com.example.user.eafya/com.example.user.eafya.activities.FirstActivity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER
Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.example.user.eafya/.activities.FirstActivity }
Error type 3
Error: Activity class {com.example.user.eafya/com.example.user.eafya.activities.FirstActivity} does not exist.

Error while Launching activity

第一个活动是清单文件中的启动器活动。

以下是build.gradle文件

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.example.user.eafya"
        minSdkVersion 17

        multiDexEnabled true
        resValue "string", "google_maps_key", (project.findProperty("GOOGLE_MAPS_API_KEY") ?: "")
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

}

Answer 1

感谢大家的贡献。这是我发现的。我将启动器活动更改为＆＃34; FirstActivity＆＃34;以外的其他活动。那也失败了，但至少它给了我一个错误：

java.lang.RuntimeException: A TaskDescription's primary color should be opaque

将原色（使用colors.xml上的颜色托盘）更改为完全不透明后，一切正常。

我调整了primary和primaryDark的透明度，这似乎是个问题。

应用无法在具有更高API的测试设备上启动
