新しいアクティビティを開始しようとしていますが、アプリが停止します。if条件がtrueの場合、登録アクティビティが実行されて機能しますが、falseの場合、追跡アクティビティはアプリを停止します。コードは次のとおりです。
if(condition)
{
Intent register = new Intent(HomeActivity.this, Register.class);
HomeActivity.this.startActivity(register);
}
else
{
Intent login = new Intent(HomeActivity.this, Track.class);
HomeActivity.this.startActivity(login);
}
多分それは私のトラッククラスの何かですか?
