## 一，安装代码 ##

private void installUseAS(String filePath) {
            File file = new File(filePath);
            Uri uri = Uri.fromFile(file);
            Intent intent = new Intent(Intent.ACTION_VIEW);
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
                intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
                Uri contentUri = FileProvider.getUriForFile(mContext, BuildConfig.APPLICATION_ID + ".fileprovider", file);
                intent.setDataAndType(contentUri, "application/vnd.android.package-archive");
            } else {
                intent.setDataAndType(uri, "application/vnd.android.package-archive");
                intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            }
            mContext.startActivity(intent);
        }

## 二，适配7.0代码FileProvider ##

### 1，Minifest中配置 ###

### 2，新建file\_paths.xml ###

            path="path" />
        //Context.getExternalCacheDir()
    </paths>
