Android 6.0 Intent installation apk flash back, androidapk

Android 6.0 Intent installation apk flash back, androidapk

Requirement Description:

Use DownloadManager in android to download the apk file and open the installation interface.

Problem description:

There are many examples of DownloadManager usage online. After the download is complete, the installation interface is opened in the android6.0 (api = 23) environment and a crash occurs (check that the configuration permission has been configured in the AndroidManifest. xml file ). It works normally in the Android4.4 (api = 19) environment. Because there are only two android phones, no other systems before android were attempted. The Code is as follows:

public static void install(Context context, String filePath) {    Intent i = new Intent(Intent.ACTION_VIEW);    i.setDataAndType(Uri.parse("file://" + filePath), "application/vnd.android.package-archive");    i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);    context.startActivity(i);}

Solution Process:

Baidu has no fruit, and google has an answer.

Solution:

After android6.0 (api = 23), open the file and let the system determine how to handle it. For detailed solutions, see the following address:

Cause analysis:

API <= 22 com.android.packageinstallerAPI >= 23 com.google.android.packageinstaller

However, after "intent. setComponent (comp);" is added to the above code, it will still crash under android6.0.
