API版本不兼容
我使用android studio制作了一个应用程序,直到现在我一直在使用Nexus 5X(API 23)模拟器进行测试#39;但是,今天我开始在三星Galaxy Tab 2 7.0(API 18)'而应用程序甚至不会启动。我知道这是因为API之间的不兼容性,特别是与我使用的主题有关。我想知道的是如何在不改变应用程序外观的情况下解决这个问题。

Gradle Build App文件
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "23.0.3"
defaultConfig {
applicationId "com.***.*******"
minSdkVersion 15
targetSdkVersion 22
versionCode 1
versionName "2.0"

testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:22.2.1'
compile 'com.android.support:design:22.2.1'
}
注意:最后两行(带有编译的那些......)用红色下划线标出&#39;这个支持库不应该使用与编译不同的版本(22) SDK版本(21)。&#39;
修改:如果我将主要活动的主题更改为&#39; @ style / Theme.AppCompat.NoActionBar&#39;然而,应用程序将启动,应用程序的外观会发生变化。此外,其他不使用新主题的活动也可以正常工作。
感谢任何帮助。
