使用

1.添加 Gradle 依赖

Download bga-update 后面的「latestVersion」指的是左边这个 Download 徽章后面的「数字」,请自行替换。 ```groovy dependencies { compile 'cn.bingoogolapple:bga-update:[email protected]'

// 换成己工程里依赖的 rxjava 和 retrofit 版本
compile 'io.reactivex:rxjava:1.3.2'
compile 'io.reactivex:rxandroid:1.2.1'
compile 'com.squareup.retrofit2:retrofit:2.3.0'
compile 'com.squareup.retrofit2:converter-gson:2.3.0'
compile 'com.squareup.retrofit2:adapter-rxjava:2.3.0'

} ```

2.在 Activity 的 onCreate 方法中监听下载进度。demo 里引用了 rxlifecycle 这个库来防止 Activity 内存泄漏

BGAUpgradeUtil.getDownloadProgressEventObservable()
        .compose(this.bindToLifecycle())
        .subscribe(new Action1() {
            @Override
            public void call(BGADownloadProgressEvent downloadProgressEvent) {
                if (mDownloadingDialog != null && mDownloadingDialog.isShowing() && downloadProgressEvent.isNotDownloadFinished()) {
                    mDownloadingDialog.setProgress(downloadProgressEvent.getProgress(), downloadProgressEvent.getTotal());
                }
            }
        });

3.下载新版 apk 文件。注意先申请 WRITEEXTERNALSTORAGE 权限

@AfterPermissionGranted(RC_PERMISSION_DOWNLOAD)
public void downloadApkFile() {
    String[] perms = {Manifest.permission.WRITE_EXTERNAL_STORAGE};
    if (EasyPermissions.hasPermissions(this, perms)) {
        // 如果新版 apk 文件已经下载过了,直接 return,此时不需要开发者调用安装 apk 文件的方法,在 isApkFileDownloaded 里已经调用了安装」
        if (BGAUpgradeUtil.isApkFileDownloaded(mNewVersion)) {
            return;
        }

    // 下载新版 apk 文件
    BGAUpgradeUtil.downloadApkFile(mApkUrl, mNewVersion)
            .subscribe(new Subscriber<file>() {
                @Override
                public void onStart() {
                    showDownloadingDialog();
                }

                @Override
                public void onCompleted() {
                    dismissDownloadingDialog();
                }

                @Override
                public void onError(Throwable e) {
                    dismissDownloadingDialog();
                }

                @Override
                public void onNext(File apkFile) {
                    if (apkFile != null) {
                        BGAUpgradeUtil.installApk(apkFile);
                    }
                }
            });
} else {
    EasyPermissions.requestPermissions(this, "使用 BGAUpdateDemo 需要授权读写外部存储权限!", RC_PERMISSION_DOWNLOAD, perms);
}

}

4.下次进入应用时删除之前升级时下载的老的 apk 文件

BGAUpgradeUtil.deleteOldApk();
