我今天开始用AndroidStudio编程，一位朋友给我发了一个小示例应用程序，但我不能运行任何代码，因为这个错误不断出现。我已经用不同的论坛解决了大约3个小时，但我无法让它开始工作，我非常感谢你的帮助，因为我只是不知道该怎么做.

将此添加到您的AndroidManifest.xml中
您需要找到带有<activity>标记的action MAIN和LAUNCHER的category标记
加上这样的android:exported="true" –
<code class="language-javascript"> <span class="token operator"><</span>activity
<span class="token literal-property property">android</span><span class="token operator">:</span>name<span class="token operator">=</span><span class="token string">".MainActivity"</span>
<span class="token literal-property property">android</span><span class="token operator">:</span>exported<span class="token operator">=</span><span class="token string">"true"</span><span class="token operator">></span>
<span class="token operator"><</span>intent<span class="token operator">-</span>filter<span class="token operator">></span>
<span class="token operator"><</span>action android<span class="token operator">:</span>name<span class="token operator">=</span><span class="token string">"android.intent.action.MAIN"</span> <span class="token operator">/</span><span class="token operator">></span>
<span class="token operator"><</span>category android<span class="token operator">:</span>name<span class="token operator">=</span><span class="token string">"android.intent.category.LAUNCHER"</span> <span class="token operator">/</span><span class="token operator">></span>
<span class="token operator"><</span><span class="token operator">/</span>intent<span class="token operator">-</span>filter<span class="token operator">></span>
<span class="token operator"><</span><span class="token operator">/</span>activity<span class="token operator">></span></code>
