编译我的 Android 项目时如何修复 java.lang.OutOfMemoryError: Java heap space ？
我在升级到 Android Studio 版本 1 后得到了这个。但是，我不认为这是问题所在。最有可能是在我开始将我的应用程序升级到 SDK 21 时（在此之前是 SDK 20）。但我也不太确定。
我在谷歌上搜索了 一些 修复 方法，但找不到有效的方法。大多数修复都是针对 Eclipse IDE 的。
这是我在编译时得到的完整 logcat 错误：
warning: Ignoring InnerClasses attribute for an anonymous inner class
(net.lingala.zip4j.unzip.Unzip$1) that doesn't come with an
associated EnclosingMethod attribute. This class was probably produced by a
compiler that did not target the modern .class file format. The recommended
solution is to recompile the class from source, using an up-to-date compiler
and without specifying any "-target" type options. The consequence of ignoring
this warning is that reflective operations on this class will incorrectly
indicate that it is *not* an inner class.

是因为我使用了一个 jar 库（zip4j）吗？我确实尝试将其删除，但仍然出现 OOM 错误。知道如何解决这个问题吗？
编辑：
我还编辑了 gradlew 文件以增加 -Xmx 大小。
GRADLE_OPTS="$GRADLE_OPTS \"-Xdock:name=$APP_NAME\" \"-Xdock:icon=$APP_HOME/media/gradle.icns\" \"-Xmx2048M \"-XX:MaxPermSize=512M\" \"-XX:ReservedCodeCacheSize=512M\""
没有什么变化。
编辑 2：
也做了 这个 修复，但也无能为力：
尝试以下操作：
Ctrl + Alt + S -> 编译器 -> Gradle
在 VM Options 字段中写入：
-Xmx2048m -XX:MaxPermSize=512m

我终于通过限制 gradle 依赖中的 Google Play 服务解决了这个问题。
不过这个问题是由Google Play服务引起的，只需将其更改为特定库即可解决。
