Question

我正在尝试在 android 工作室中开发对象检测应用程序，但它给我一个错误。错误在这一行 android:theme="@style/MaterialTheme"

manifest.xml

    <uses-permission android:name="android.permission.CAMERA" />
    <uses-feature android:name="android.hardware.camera" />
    <uses-feature android:name="android.hardware.camera.autofocus" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

    <uses-sdk
        android:minSdkVersion="21"
        android:targetSdkVersion="23" />

            </intent-filter>
        </activity>

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

            </intent-filter>
        </activity>
    </application>

</manifest

Answer 1

只是给出一个可能对其他人稍后提出的问题有帮助的答案。如果您不需要任何自定义主题，则可以删除该属性。如果 res/values 中不存在，则创建一个 style.xml 并检查该特定 <style></style> 资源是否存在。如果没有，那么您可以创建一个。希望这有帮助。
