活動を開始することができませんメインI持ってmainactivityに次のコード：エラー：致命的な例外：ComponentInfo
：Intent profile = new Intent(mContext, ProfileActivity.class);
mContext.startActivity(profile);
それは私に次の例外を与える：

mPreview = new Preview(this, mDraw);
mDraw.mTracker = new HTracker();

申し訳ありません。以下を追加してください。 ProfileActivityコードは空のアクティビティです。彼は、コード
import android.app.Activity;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
public class ProfileActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_profile);
}
}
ですそして、私のマニフェストには、次のとおりです。
<?xml version="1.0" encoding="utf-8"?>

誰も私を助けることができる、してください？
これは、「原因：java.lang.IllegalStateException：このアクティビティでTheme.AppCompatテーマ（または子孫）を使用する必要があります」を検索する際のエラーです。スタックトレースを読み込むには、「原因」を探します。 。常に –
また、ProfileActivityに問題があります。 – Selvin
