提问by BArtWell
I get this error in Eclipse: Call requires API level 14 (current min is 8): android.app.ActionBar#setHomeButtonEnabled
我在 Eclipse 中收到此错误：Call requires API level 14 (current min is 8): android.app.ActionBar#setHomeButtonEnabled
This is code:
这是代码：
if(android.os.Build.VERSION.SDK_INT>=14) {
getActionBar().setHomeButtonEnabled(false);
}
In Manifest:
在清单中：
<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="14" />

Add the line @TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH)above the method signature, where Build.VERSION_CODES.ICE_CREAM_SANDWICHevaluates to 14, the API version code for Ice Cream Sandwich.
@TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH)在方法签名上方添加一行，其中的Build.VERSION_CODES.ICE_CREAM_SANDWICH计算结果为 14，即 Ice Cream Sandwich 的 API 版本代码。
Like so:
像这样：
@TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH)
public void yourMethod() {
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
getActionBar().setHomeButtonEnabled(false);
}
}

Note: the accepted answeris outdated.
注意：接受的答案已过时。
In Android Studio 3.0 Beta 7you don't need the @TargetApiannotation anymore.
It seems that the lint check is smarter now.
在Android Studio 3.0 Beta 7您不再需要@TargetApi注释。
现在看来 lint 检查更智能了。
So this is enough:
所以这就足够了：
public void yourMethod() {
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
getActionBar().setHomeButtonEnabled(false);
}
}
