camera2+MediaRecorderで録画するアプリ　録画ボタンを押すとアプリが強制終了してしまいます。

前提・実現したいこと

camera2+MediaRecorderでボタンを押したときに映像を5秒間録画するアプリが作成したいです。

起きている問題

ボタンを押した時に、アプリが強制終了してしまいます。
終了したときのログを確認して、MediaRecorderが正常に
動作できていないのは分かったのですが、根本的な解決法が分かりませんでした。
エラー解決の方法など教えていただけないでしょか。

//追記
public void onClick(View v) {内のmRecorder.start();でRuntimeInit.javaに飛びアプリが終了していました。
