Android应用程序仅在低Android API上在OnCreate的setContentView时崩溃
[英]Android application crashes at setContentView at OnCreate only on low android API
问题描述
我的应用程序在API 24及更高版本上运行，但在API 19上崩溃。问题似乎出在OnCreate方法的setContentView行。
我试图更改android XML文件中的所有API 21+功能，但没有帮助。 还尝试放入multidex，但没有用。
我在这里添加了setContentView方法：

stacktrace似乎指示读取当前资源配置时出现问题（无论您的语言环境是否为RTL）。
查看活动代码，您正在修改应用程序使用的语言环境，而不是使用可以解释该问题的电话语言环境。 您的活动实际上将进行两次onCreate 。 第一次可能是使XML视图膨胀而没有任何麻烦，但是一旦您设置了新的Configuration（通过调用loadLocale() ），该Activity将被销毁并重新创建，它将使用新的Configuration第二次执行onCreate() 。 这是您的应用程序崩溃时。
我认为问题很可能出在setLocale()方法中，配置更改未正确完成，新的API可以使用默认值，而旧的API只会崩溃。
即使我不建议您在应用程序中修改语言环境，这里还是有关在Android应用程序中修改语言环境的更多信息：
https://proandroiddev.com/change-language-programmatically-at-runtime-on-android-5e6bc15c758
根据您支持的API版本，可以使用不同的方法。
他用来更改配置的方法如下所示：
private static Context updateResources(Context context, Locale locale) {
Locale.setDefault(locale);
Resources res = context.getResources();
Configuration config = new Configuration(res.getConfiguration());
if (Build.VERSION.SDK_INT >= 17) {
config.setLocale(locale);
context = context.createConfigurationContext(config);
} else {
config.locale = locale;
res.updateConfiguration(config, res.getDisplayMetrics());
}
return context;
}
