【描述】:更新Android SDK为API21（5.0）后，Graphics视图不可见了，出现如下问题："Loading data for Android 5.0" has encountered a problem. Parsing Data for android-21 failed unsupported major.minor version 51

Eclipse的工程下.settings隐藏目录多了些文件：.org.eclipse.jdt.core.prefs,eclipse.preferences.version=1org.eclipse.jdt.core.compiler.codegen.targetPlatform=1.5org.eclipse.jdt.core.compiler.compliance=1.5org.

eclipse有一个小工具和查看heap的状态,并且可以手动执行GC.
