MediaStore.ACTION_IMAGE_CAPTURE无法调起相机应用

Question

点击按钮后，无法调起相机，直接退出对应Activity，请教原因!!!
代码：
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent capIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(capIntent,100);
}
});

AndroidManifest.xml:
    <uses-permission android:name="android.permission.CAMERA"></uses-permission>
<uses-feature android:name="android.hardware.camera2"></uses-feature>
