在 Smart Lock 示例应用程序中使用库 com.android.support:design:23.1.1+ 时出现错误

Question

我从 Google 下载了应用程序示例 Smart Lock for passwords。除了使用库 <= 23.0.1 之外还有其他解决方案吗？

库中有错误？

使用库时出现错误com.android.support:design:23.1.1+:

Answer 1

Android compileSdkVersion is the version of the compiler used in building the Application .The Android Support Library package is a set of code libraries that provide backward-compatible versions of Android framework APIs as well as features that are only available through the library APIs.

对于compileSdkVersion 23可以使用波纹管

调用+不是好的方法

compile 'com.android.support:design:23.0.0'
compile 'com.android.support:design:23.0.1'
compile 'com.android.support:design:23.1.0'
compile 'com.android.support:design:23.1.1'
compile 'com.android.support:design:23.2.0'
compile 'com.android.support:design:23.2.1'

在 Google 这个例子中，我在 MainActivity 中更改了以下代码，java:

    private void setFragment(Intent intent) {
    ...
    if (currentTag == null || !currentTag.equals(tag)) {
        getSupportFragmentManager().beginTransaction()
                .replace(R.id.fragment_container, fragment, tag)
                .commit();
    }
}

收件人：

    private void setFragment(Intent intent) {
    ...
    if (currentTag == null || !currentTag.equals(tag)) {
        getSupportFragmentManager().beginTransaction()
                .replace(R.id.fragment_container, fragment, tag)
                .commitAllowingStateLoss();
    }
}

在 Smart Lock 示例应用程序中使用库 com.android.support:design:23.1.1+ 时出现错误

Error occurs when you use the library com.android.support:design:23.1.1+ in Smart Lock sample app
