在非Activity中使用startActivity：Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag
問題描述
在APP 1中啟動(dòng)APP 2中的Activity舒岸。
Intent intent = new Intent(Intent.ACTION_VIEW);
Uri uri1 = Uri.parse("xxxx://xxxx/page/link?url=http%3A%2F%2Fwww.baidu.com");
intent.setData(uri1);
Context context = getApplicationContext();
if (null != intent.resolveActivity(pm)) {
context.startActivity(intent);
}
錯(cuò)誤提示信息:
Caused by: Android.util.AndroidRuntimeException: Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?
原因分析
activity繼承了context重載了startActivity方法,如果使用acitvity中的startActivity，不會(huì)有任何限制。
而如果直接使用context的startActivity則會(huì)報(bào)上面的錯(cuò)誤，根據(jù)錯(cuò)誤提示信息,可以得知,如果要使用這種方式需要打開新的TASK。
解決方法:
加上Flags
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
Intent intent = new Intent(Intent.ACTION_VIEW);
Uri uri1 = Uri.parse("xxxx://xxxx/page/link?url=http%3A%2F%2Fwww.baidu.com");
intent.setData(uri1);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
Context context = getApplicationContext();
if (null != intent.resolveActivity(pm)) {
context.startActivity(intent);
}
