Android Studio项目适用于Lollipop,但不适用于Kitkat

我有一个Android Studio项目在Android版本Lollipop的设备上正常工作,但是在尝试使用Android构建版本Kitkat的设备上运行它时会抛出异常.这是我的项目的build.gradle文件:

android {

    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 21

            renderscriptTargetApi 22

谁知道怎么解决这个问题？

eya*_*nna 12

如果有人到这里,我就是这样解决问题的.

在我深入研究了这个问题之后,我发现它不是一个膨胀的例外,虽然这就是logcat所说的,真正的例外是由臭名昭着的65K问题引起的OutOfMemory异常点击这里获取有关该问题的更多信息并且它被包裹着膨胀的兴奋.

为了解决这个问题,我首先在build.gradle文件中添加了multidex支持库:

compile 'com.android.support:multidex:1.0.0'
Run Code Online (Sandbox Code Playgroud)

然后我按照这三个简单的步骤使其工作:

  1. 如果您没有自己实现Application类,只需在应用程序标记下的Android Manifest文件中定义库的MultiDexApplication:

    机器人:名字= "android.support.multidex.MultiDexApplication"

  2. 如果要实现自己的Application类,则可以简单地覆盖MultiDexApplication文件:

    公共类MyAwesomeApplication扩展MultiDexApplication {

  3. 或者,如果您的应用程序类已经扩展了另一个类,您可以覆盖attachBaseContext方法并向其添加以下调用:

    @Override protected void attachBaseContext(Context base){super.attachBaseContext(context); Multidex.install(本); }

我已经拥有了自己的应用程序类,它从"应用程序"类扩展而来,所以我直接跳到了第3步,并且它在Kitkat和Lollipop上工作了.

希望这有助于任何人.快乐的编码.
