Jar mismatch! Fix your dependencies
在eclipse建立android專案的時候,預設會帶有一個android-support-v4.jar，當你匯入其他開源庫專案的時候，這會有兩個這種架包，所以刪掉一個即可
解決：把你專案的libs包下的android-support-v4.jar刪掉即可
2、The type android.support.v4.app.FragmentActivity cannot be resolved.
這個問題可能有兩種情況：1，可能是你沒有正確匯入庫專案，庫專案必須和你的專案在同一個碟符下，
2，可能 你的v4包有兩個，衝突了。
