android 7.0适配（总结）

file_paths.xml

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:andro />
</paths>

原：

Uri uri = Uri.fromFile(new File(filename));
Intent localIntent = new Intent(Intent.ACTION_VIEW);
localIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
localIntent.setDataAndType(uri, "application/vnd.android.package-archive");
startActivity(localIntent);

修改后：

Intent localIntent = IntentUtils.getInstallAppIntent(new File(filename), true);

localIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

startActivity(localIntent);

public static Intent getInstallAppIntent(final File file, final boolean isNewTask) {
    if (file == null) return null;
    Intent intent = new Intent(Intent.ACTION_VIEW);
    Uri data;
    String type = "application/vnd.android.package-archive";
    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.N) {
        data = Uri.fromFile(file);
    } else {
        intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
        String authority = Utils.getApp().getPackageName() + ".utilcode.provider";
        data = FileProvider.getUriForFile(Utils.getApp(), authority, file);
    }
    intent.setDataAndType(data, type);
    return getIntent(intent, isNewTask);
}

7.0 WebView 部分机型打不开 （未尝试）

https 请求 webview 有 证书校验

@Override
public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
if (error.getPrimaryError() == SslError.SSL_DATE_INVALID
|| error.getPrimaryError() == SslError.SSL_EXPIRED
|| error.getPrimaryError() == SslError.SSL_INVALID
|| error.getPrimaryError() == SslError.SSL_UNTRUSTED) {
handler.proceed();
} else {
handler.cancel();
}
super.onReceivedSslError(view, handler, error);
}
通过重写:
onReceivedSslError 过滤掉 部分错误
SSL_DATE_INVALID 证书的日期是无效的
SSL_EXPIRED 证书已经过期
SSL_INVALID 一个通用的错误发生
SSL_UNTRUSTED 不受信任的证书颁发机构
