我是QT的新手，并且正在尝试构建一个简单的Android应用程序。我使用QT 5.7使用评估包QT Creator 4.2.0（企业）。由于某种原因，在我通过项目 -> build设置 -> build android apk'创建模板'创建AndroidManifest.xml之后，我在编译后会遇到以下错误。/strong>"

我尝试在makefile中查看，但目录都看起来还不错。没有类型。
我的.pro文件如下：

我似乎没有使用QT 5.1。
没有问题。任何帮助都很好！
谢谢
存在类似的问题，也存在https://bugreports.qt.io/browse/qtcreatorbug-13566，它是通过禁用不必要的" make install"one_answers" build" build apk septs on fine构建设置下的项目模式。
根据qt源qmakeandroidbuildapkstep.cpp，有2个情况，其中有一条消息：.pro文件找不到并部署设置.json文件找不到
const QmakeProjectManager::QmakeProFileNode *node = pro->rootProjectNode()->findProFileFor(proFilePathForInputFile());
m_skipBuilding = !node;
if (m_skipBuilding)
return true;
QString inputFile = node->singleVariableValue(QmakeProjectManager::Variable::AndroidDeploySettingsFile);
if (inputFile.isEmpty()) {
m_skipBuilding = true;
return true;
}
我已经查看了JSON文件并在内部找到了一条消息 - 它打算由AndroidDeployQT读取。下一步非常简单：
/opt/Qt/5.9/android_armv7/bin/androiddeployqt --input android-libretroshare-qml-app.so-deployment-settings.json --release --verbose --gradle --stacktrace --debug --output ./
它根本无法解决我的问题，但是它的消息非常有帮助。
