Question

我有一个使用人行横道的android / cordova项目。当我尝试构建时，我有以下错误：

// Set the dimensions of the canvas / graph
var margin = {
    top: 30,
    right: 20,
    bottom: 30,
    left: 50
  },
  width = 800 - margin.left - margin.right,
  height = 500 - margin.top - margin.bottom;

// Parse the date / time
var parseDate = d3.time.format("%b %Y").parse;

// Set the ranges
var x = d3.time.scale().range([0, width]);
var y = d3.scale.linear().range([height, 0]);

// Define the axes
var xAxis = d3.svg.axis().scale(x)
  .orient("bottom");

var yAxis = d3.svg.axis().scale(y)
  .orient("left");

var line = d3.svg.line()
  .interpolate("basis")
  .x(function (d) {
    return x(d.date);
  })
  .y(function (d) {
    return y(d.value);
  });

// Adds the svg canvas
var svg = d3.select("#d3-line-chart")
  .append("svg")
  .attr("width", width + margin.left + margin.right)
  .attr("height", height + margin.top + margin.bottom)
  .append("g")
  .attr("transform",
    "translate(" + margin.left + "," + margin.top + ")");

//get the data
d3.csv("test.csv", function (error, data) {
  var res = [];
  var cols = d3.keys(data[0])
    .filter(function (key) {
      return key;
    });

  for (var j = 0; j < cols.length - 1; j++) {
    var col = cols[j];
    var row = [];
    for (var i = 0; i < data.length; i++) {
      row.push({
        symbol: col,
        date: data[i]["date"],
        value: +data[i][col]
      });
    }
    res.push(row);
  }

  // Scale the range of the data
  x.domain(d3.extent(res, function (d) {
    return d.date;
  }));
  y.domain([0, d3.max(res, function (d) {
    return d.value;
  })]);


  svg.selectAll(".line")
    .data(res)
    .enter().append("path")
    .attr("class", "line")
    .attr("d", line);

  // Add the X Axis
  svg.append("g")
    .attr("class", "x axis")
    .attr("transform", "translate(0," + height + ")")
    .call(xAxis);

  // Add the Y Axis
  svg.append("g")
    .attr("class", "y axis")
    .call(yAxis);

});

但我在我的config.xml中设置了ver17：

:processArmv7DebugManifest/app/platforms/android/AndroidManifest.xml:31:5-74 Error:
    uses-sdk:minSdkVersion 15 cannot be smaller than version 16 declared in library [org.xwalk:xwalk_core_library:20.50.533.12] /app/platforms/android/build/intermediates/exploded-aar/org.xwalk/xwalk_core_library/20.50.533.12/AndroidManifest.xml
    Suggestion: use tools:overrideLibrary="org.xwalk.core" to force usage


See http://g.co/androidstudio/manifest-merger for more information about the manifest merger.

:processArmv7DebugManifest FAILED

FAILURE: Build failed with an exception.

* What went wrong:

BUILD FAILED

此外，它在platforms / android / AndroidManifest.xml中是相同的：

   <preference name="android-minSdkVersion" value="17" />
    <preference name="android-targetSdkVersion" value="17" />

我试图移除然后再添加回人行横道和平台android＆＃34;本身，但错误仍然存在。

请帮忙

Answer 1

这似乎是新的Crosswalk版本的一个问题，他们取消了对较旧的Andorid API的支持。将config.xml中的Crosswalk版本更改为先前版本19解决了我的问题

<preference name="xwalkVersion" value="19" />

Answer 2

尝试使用minSdkVersion标志构建：

cordova build android -- --minSdkVersion=16

注意双重 - 是有意的
