Android SDK をアップグレードしてからjava.lang.VerifyError
、以前に動作していたアプリケーションを起動するとクラッシュします。
ログを見ると、以前にはなかったクラッシュにつながるいくつかの新しい問題があります。
Could not find method android.support.v4.content.LocalBroadcastManager.getInstance, referenced from method com.myapp.android.App.setOAuthLoginState

android.support.v4.content.LocalBroadcastManager.getInstance
Android Compatibilty ライブラリのソース コードにまだ含まれているようです。この警告は、App.onCreate() が BTW と呼ばれる前に記録されます。
android-support-v4.jar
以前にアプリケーションで動作していた の古いバージョンとandroid-support-v4.jar
、最新の SDK に含まれている の新しいバージョンの両方を使用してみましたが、どちらの場合も結果は同じです (興味深いと思いますよね?)。
また、次のような警告の流れも奇妙です。
W/dalvikvm(12455): VFY: unable to find class referenced in signature (Ltwitter4j/User;)
ここで参照されている twitter4j ライブラリは、私のプロジェクトに正しく含まれているようです。
私はまだ Java を学んでいるので、何がこの問題を引き起こしているのかわかりません。どんな助けでも大歓迎です。
