将 Eclipse 项目导入 Android Studio答案

【问题标题】：Importing Eclipse Project to Android Studio将 Eclipse 项目导入 Android Studio
【发布时间】：2016-05-15 14:11:00
【问题描述】：

由于 ADT 插件现已过时，我正在将我的 Eclipse 项目转换为 Android Studio。对于前三个，一切正常，但我现在尝试转换的那个有问题：由于“libpng 错误：不是 png 文件”，gradle 无法编译我的代码。

我已经看到我不是第一个遇到这个问题的人（我已经看到了三四个关于这个问题的 StackOverflow 问题），但我到目前为止还没有找到解决方案。我不知道哪个 png 文件会导致错误，我可以补充说我的文件夹中没有“.9”图像（Android 库中的图像除外）。

如果一个 png 文件确实是问题的原因，我怎么能得到它的名字？

【问题讨论】：

你做了什么将eclipse项目转换为Android Studio项目？
我使用“文件-新建-导入项目”。
我在 Gradle 中添加了“--info”选项，可以看到与错误相关的三个图像名称。奇怪的是，这三张图片来自android网站（“ic_action_search”）。我用 Paint 和 Gimp 编辑它们并将它们保存为 png 格式：没有改进... 其他尝试：我已经用“ic_launcher”图标替换了这三个图像，但现在，我仍然收到错误但我没有得到任何错误图像的名称。
在导入之前连接到 Internet
我做到了：同样的句子，不幸的是......

标签： android eclipse android-studio

【解决方案1】：

问题实际上与“png”图像格式有关。由于我找不到错误图像的名称，因此我逐个复制它们，并在每次添加一些图像时构建项目。最后，我在 418 中只找到了一张导致问题的图像！！
