以下のスタック トレースに似たスタック トレースを含む Crittercism クラッシュ レポートをいくつか受け取りました。クラッシュは私のコードが原因ではありません。
このフォーラムの投稿は、TextView のカスタム OEM 実装のバグが原因である可能性があることを示唆しています:

これが事実であるかどうか、誰でも確認できますか？影響を受けるユーザーはごくわずかですが、修正/回避策があるかどうか知りたいですか?
これまでのところ、私のクラッシュ レポートには、次のデバイスが影響を受けていることが示されています。
- OS 2.3.6 上の ALCATEL ONE TOUCH 903
- OS 2.3.6 上の ALCATEL ONE TOUCH 918D
- OS 2.3.6 上の ALCATEL ONE TOUCH 991D
- OS 2.3.5 上のオウム
- OS 2.3.4 上の A102S_MULA
- OS 2.3.5 上の T9199+
- OS 2.3.6 上のトライデント A7
