错误：任务'：app：ndkBuild'的执行失败。 ＆GT;启动进程'命令'ndk-build.cmd''出现问题

Question

我已经尝试了一切来解决这个问题，但我仍然不能。这是可能导致问题的build.gradle：app部分：

NDK_TOOLCHAIN_VERSION := 4.9 ( was 4.8)

我也改变了这个：

ndk.dir=C:\Users\Elyes\AppData\Local\Android\Sdk\ndk-bundle
sdk.dir=C:\Users\Elyes\AppData\Local\Android\Sdk

当然：

Imports System.IO
Imports System.IO.Compression
Imports System
Imports System.Windows.Forms
Imports System.Net
Imports System.Diagnostics
Public Class Form4
Dim tempdir As String = "C:\MediaZip"

Private Sub Form4_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    Form1.Hide()
    Me.BringToFront()
    IO.Directory.Delete(tempdir, True)
End Sub

Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
    ProgressBar1.Show()
    Timer1.Start()
    TextBox2.Text = TextBox2.Text + "\" + TextBox3.Text
    ' Create ZIP from "source" directory (in program folder).
    ZipFile.CreateFromDirectory("C:\MediaZip",
                                TextBox2.Text + ".zip",
                                CompressionLevel.Optimal,
                                False)
    MessageBox.Show("The Process are complete", "MediaZip", MessageBoxButtons.OK, MessageBoxIcon.Warning)
    ProgressBar1.Hide()
End Sub

Private Sub Button3_Click(sender As Object, e As EventArgs) Handles Button3.Click
    Dim dialog As New FolderBrowserDialog()
    dialog.RootFolder = Environment.SpecialFolder.Desktop
    dialog.SelectedPath = "C:\"
    dialog.Description = "Were To Store Your File ?"
    If dialog.ShowDialog() = Windows.Forms.DialogResult.OK Then
        TextBox2.Text = dialog.SelectedPath
    End If
    TextBox2.Text = dialog.SelectedPath
    Dim logDirectoryProperties As System.IO.DirectoryInfo

    My.Computer.FileSystem.CopyFile(
       TextBox1.Text,
       "C:\MediaZip\" + TextBox4.Text)
End Sub

 Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    Dim OpenFileDialog1 As New OpenFileDialog
    OpenFileDialog1.InitialDirectory = "C:\"
    OpenFileDialog1.FileName = "File To Zip..."
    OpenFileDialog1.Multiselect = True
    If OpenFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then
        Dim sName As String = OpenFileDialog1.SafeFileName
        TextBox1.Text = OpenFileDialog1.FileName
        TextBox4.Text = System.IO.Path.GetFileName(OpenFileDialog1.FileName)
        IO.Directory.Delete(tempdir, True)
    End If
 End Sub
End Class

它仍然不起作用。

我在windows pc上使用以下命令

task buildNative(type: Exec) {
  workingDir 'jni'// directory app/jni
  commandLine("${android.ndkDirectory}\\ndk-build.cmd", '-j', Runtime.runtime.availableProcessors())
}
