Android Studio NDK：無法加載庫“ libgnustl_shared.so”

Question

我使用新的gradle-undefined參照Android Studio 1.3+按照OpenCv的說明進行了所有操作。 但是我有錯誤“無法加載庫“ libgnustl_shared.so””。 誰知道我該如何解決這個問題？

我的build.gradle文件：

應用插件：“ com.android.model.application”

            model {
                android {
                    compileSdkVersion = 23
                    buildToolsVersion = "23.0.2"

                    defaultConfig.with {
                        applicationId = "com.atapy.wisetrend3"
                        minSdkVersion.apiLevel = 11
                        targetSdkVersion.apiLevel = 23
                        versionCode = 1
                        versionName = "1.0"

                    }
                }

                android.ndk {
                    moduleName = "rrdecoder"
                    cppFlags.add("-std=c++11")
                    cppFlags.add("-fexceptions")
                    cppFlags.add("-I${file("D:/Android/OpenCV-3.1.0-android-sdk/OpenCV-android-sdk/sdk/native/jni/include")}".toString())
                    ldLibs.addAll(["android", "EGL", "GLESv2", "dl", "log", "z"])
                    stl = "gnustl_shared"
                }

                android.buildTypes {
                    release {
                        minifyEnabled = false
                        proguardFiles.add(file("proguard-rules.txt"))
                    }
                }

                android.productFlavors {
                    create("arm") {
                        ndk.with{
                            abiFilters.add("armeabi")

                            File curDir = file('./')
                            curDir = file(curDir.absolutePath)
                            String libsDir = curDir.absolutePath + "\\src\\main\\jniLibs\\armeabi\\"

                            ldLibs.add(libsDir + "libopencv_core.a")
                            ldLibs.add(libsDir + "libopencv_highgui.a")
                            ldLibs.add(libsDir + "libopencv_imgproc.a")
                            ldLibs.add(libsDir + "libopencv_java3.so")
                            ldLibs.add(libsDir + "libopencv_ml.a")

                        }
                    }
                    create("armv7") {
                        ndk.with {
                            abiFilters.add("armeabi-v7a")

                            File curDir = file('./')
                            curDir = file(curDir.absolutePath)
                            String libsDir = curDir.absolutePath + "\\src\\main\\jniLibs\\armeabi-v7a\\"
                            ldLibs.add(libsDir + "libopencv_core.a")
                            ldLibs.add(libsDir + "libopencv_highgui.a")
                            ldLibs.add(libsDir + "libopencv_imgproc.a")
                            ldLibs.add(libsDir + "libopencv_java3.so")
                            ldLibs.add(libsDir + "libopencv_ml.a")
                            ldLibs.add(libsDir + "libopencv_ts.a")

                        }
                    }
                }
                android.sources {
                    main {
                        jni {
                            source {
                                srcDirs += ['src/main/jniMy']
                            }
                        }
                    }
                }
            }
            dependencies {
                compile fileTree(dir: "libs", include: [$/*.jar/$])
                compile "com.android.support:appcompat-v7:23.1.1"

Answer 1

如果您不介意使用gradle實驗版本升級，我在這里發布了一個示例腳本，該示例鏈接到opencv並使用gnustl_shared：將項目遷移到新的實驗gradle插件0.6.0-alpha3-> 0.6.0-alpha5

Answer 2

我下載了一組用於Linux的庫libstdc ++，並將libgnustl_shared.so放在jniLibs文件夾中。 並在加載其他庫之前調用System.loadLibrary（“ gnustl_shared”）。 有用！
