最近项目Android编译版本改为targetSdkVersion26, 之前隐藏的版本问题暴露出来, 尤其是文件第三方打开及Apk更新问题,这里记录下7.0以后文件相关问题
问题描述:
安装apk的代码一般写法如下，网上随处可以搜到:
public static void installApk(Context context, File file) { Intent intent = new Intent(Intent.ACTION_VIEW); Uri data = Uri.fromFile(file); intent.setDataAndType(data, "application/vnd.android.package-archive"); context.startActivity(intent); }
然而，当我们在Android7.0手机中执行时，会发现报如下错误日志
Caused by: android.os.FileUriExposedException: file:///storage/emulated/0/Android/data/net.csdn.blog.ruancoder/cache/test.apk exposed beyond app through Intent.getData() at android.os.StrictMode.onFileUriExposed(StrictMode.java:1799) at android.net.Uri.checkFileUriExposed(Uri.java:2346) at android.content.Intent.prepareToLeaveProcess(Intent.java:8933) at android.content.Intent.prepareToLeaveProcess(Intent.java:8894) at android.app.Instrumentation.execStartActivity(Instrumentation.java:1517) at android.app.Activity.startActivityForResult(Activity.java:4224) at android.support.v4.app.BaseFragmentActivityJB.startActivityForResult(BaseFragmentActivityJB.java:50) at android.support.v4.app.FragmentActivity.startActivityForResult(FragmentActivity.java:79) at android.app.Activity.startActivityForResult(Activity.java:4183) at android.support.v4.app.FragmentActivity.startActivityForResult(FragmentActivity.java:859) at android.app.Activity.startActivity(Activity.java:4507) at android.app.Activity.startActivity(Activity.java:4475)
